+ * MODULE:      plist.c
+ *
+ * DESCRIPTION:
+ *
+ *      This module implements property lists.  A property list is an
+ *      ordered array of property values.  Each property value has an
+ *      handle for some data item, and may have a reference to
+ *      another property list which describes the type of the data
+ *      item.  Each property value has a property index which specifies
+ *      its position in the property list.  A property value may also
+ *      have a name.  Since the data item associated with a property
+ *      value may reference another property list, it is possible to
+ *      construct arbitrary linked structures of property lists.
+ *
+ * IMPLEMENTATION NOTES:

+# This file configures how a certificate is mapped to an LDAP entry.  See the
+# documentation for more information on this file.
+#
+# The format of this file is as follows:
+#	certmap <name> <issuerDN>
+#	<name>:<prop1> [<val1>]
+#	<name>:<prop2> [<val2>]
+#
+# Notes:
+#
+# 1.  Mapping can be defined per issuer of a certificate.  If mapping doesn't
+#     exists for a particular 'issuerDN' then the server uses the default
+#     mapping. 
+#
+# 2.  There must be an entry for <name>=default and issuerDN "default".
+#     This mapping is the default mapping.
+#
+# 3.  '#' can be used to comment out a line.
+#
+# 4.  DNComps & FilterComps are used to form the base DN and filter resp. for 
+#     performing an LDAP search while mapping the cert to a user entry.
+#
+# 5.  DNComps can be one of the following:
+#	commented out - take the user's DN from the cert as is
+#	empty         - search the entire LDAP tree (DN == suffix)
+#	attr names    - a comma separated list of attributes to form DN
+#
+# 6.  FilterComps can be one of the following:
+#	commented out - set the filter to "objectclass=*"
+#	empty         - set the filter to "objectclass=*"
+#	attr names    - a comma separated list of attributes to form the filter

+This directory contains an example program to demonstrate
+writing plugins using the "Certificate to LDAP Mapping" API.
+Please read the "Managing Netscape Servers" manual to find out
+about how certificate to ldap mapping can be configured using
+the <ServerRoot>/userdb/certmap.conf file.  Also refer to the
+"Certificate to LDAP Mapping API" documentation to find out
+about the various API functions and how you can write your
+plugin.
+
+This example demonstrate use of most of the API functions.  It
+defines a mapping function, a search function, and a verify
+function.  Read the API doc to learn about these functions.
+The init.c file also contains an init function which sets the
+mapping, search and verify functions.
+
+The Mapping Function 
+-------------------- 
+
+The mapping function extracts the attributes "CN", "E", "O" and
+"C" from the certificate's subject DN using the function
+ldapu_get_cert_ava_val.  If the attributes "C" doesn't exists
+then it defaults to "US".  It then gets the value of a custom
+certmap.conf property "defaultOU" using the function
+ldapu_certmap_info_attrval.  This demonstrates how you can have
+your own custom properties defined in the certmap.conf file.
+The mapping function then returns an ldapdn of the form:
+"cn=<name>, ou=<defaultOU>, o=<o>, c=<c>".
+
+If the "E" attribute has a value, it returns a filter
+"mail=<e>".  Finally, the mapping function frees the structures
+returned by some of the API functions it called.
+
+
+The Search Function
+-------------------
+
+The search function calls a dummy function to get the
+certificate's serial number.  It then does a subtree search in
+the entire directory for the filter 
+"certSerialNumber=<serial No.>".  If this fails, it calls the
+default search function.  This demonstrates how you can use the
+default functions in your custom functions.
+
+The Verify Function
+-------------------
+
+The verify function returns LDAPU_SUCCESS if only one entry was
+returned by the search function.  Otherwise, it returns
+LDAPU_CERT_VERIFY_FUNCTION_FAILED.
+
+
+Error Reporting
+---------------
+
+To report errors/warning, there is a function defined called
+plugin_ereport.  This function demonstrates how to get the
+subject DN and the issuer DN from the certificate.
+
+Build Procedure
+---------------
+On UNIX: Edit the Makefile, and set the variables ARCH & SROOT
+according to the comments in the Makefile.  Download LDAP SDK
+from the Netscape's DevEdge site and make the ldap include
+files available in <SROOT>/include.  Copy the
+../include/certmap.h file to the <SROOT>/include directory.
+Use 'gmake' to build the plugin.  A shared library plugin.so
+(plugin.sl on HP) will be created in the current directory.
+
+On NT:  Execute the following command:
+NMAKE /f "Certmap.mak" CFG="Certmap - Win32 Debug"
+Certmap.dll will be created in the Debug subdirectory.
+
+Certmap.conf Configuration
+--------------------------
+Save a copy of certmap.conf file.
+Change the certmap.conf file as follows:
+
+certmap default default
+default:defaultOU   marketing
+default:library	    <path to the shared library>
+default:InitFn	    plugin_init_fn
+
+
+After experimenting with this example, restore the old copy of
+certmap.conf file.  Or else, set the certmap.conf file as follows:
+
+certmap default default
+default:DNComps	    
+default:FilterComps	e, mail, uid
+default:VerifyCert	on

+
+
+<P>Last Update: Aug 25, 1997
+
+<P>All the new changes have been checked into the server3_tier_branch.&nbsp;
+The server3_branch is frozen &amp; contains the version of 'ldaputil' for
+the SuiteSpot 3.0 release.
+<H2>
+Changed:</H2>
+Several bug fixes went in since I last modified this file.&nbsp; The important
+ones are:
+<UL>
+<LI>
+<A HREF="http://scopus/bugsplat/show_bug.cgi?id=79373">79373</A>: Attributes
+listed multiple times in certmap.conf were turining that attribute off
+and enabling some other attribute.&nbsp; (For example, if you have "E"
+as well as "MAIL" in FilterComps, they cancelled each other).</LI>
+
+<LI>
+<A HREF="http://scopus/bugsplat/show_bug.cgi?id=58474">58474</A>: If nested
+group checks goes on for 30 recursions, a circular groups error is returned.</LI>
+
+<LI>
+<A HREF="http://scopus/bugsplat/show_bug.cgi?id=80004">80004</A>: after
+thoroughly testing the certmap utility, several (mostly minor) oddities
+were found &amp; fixed.</LI>
+</UL>
+
+<H2>
+Added:</H2>
+
+<UL>
+<LI>
+<A HREF="http://scopus/bugsplat/show_bug.cgi?id=79370">79370</A>: Group
+membership check is optimized now through the new function <B>ldapu_auth_userdn_groupids</B>.&nbsp;
+Use this new function to get the optimization.&nbsp; This function's algorithm
+is as follows:</LI>
+
+<BR>The first search uses the following filter (w/o the group names!):
+<OL><TT>(| (&amp; (objectclass=groupofuniquenames)</TT>
+<BR><TT>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (uniquemember=&lt;userDN>))</TT>
+<BR><TT>&nbsp;&nbsp; (&amp; (objectclass=groupofnames)(member=&lt;userDN>)))</TT>
+<BR>&nbsp;</OL>
+This gives us all the groups the user is member of.&nbsp; We ask for only
+the "CN" attributes of the returned groups.&nbsp; We check if "CN" of any
+of the returned groups is one of the groups we have.&nbsp; If yes, we have
+succeeded.&nbsp; If there are no groups returned then we have failed.&nbsp;
+Otherwise, we continue with the nested group check.&nbsp; To perform that
+check, we need DNs of all the groups the user is member of, which we already
+have from the previous search.&nbsp; Now we repeat the search as follows:
+<OL><TT>(| (&amp; (objectclass=groupofuniquenames)</TT>
+<BR><TT>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (| (uniquemember=&lt;grp1DN>)...
+(uniquemember=&lt;grpNDN>))</TT>
+<BR><TT>&nbsp;&nbsp; (&amp; (objectclass=groupofnames)</TT>
+<BR><TT>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (| (member=&lt;grp1DN>)... (member=&lt;grpNDN>))</TT></OL>
+We check the list of groups returned by this search with the groups in
+the ACL and recursively continue until we succeed or no more groups are
+returned from the searches.
+
+<P>Advantages of this new function is it checks multiple groups at the
+same time.&nbsp; Previously we were performing 2 ldap lookups per group.&nbsp;
+Now we achieve this in a single ldap lookup!
+
+<P><B><BLINK>Caution</BLINK></B>: this function allows multiple groups
+with the same "CN".
+
+<P>To use this function, you need to provide a list of group names in any
+form (e.g comma separated string, a hash table, array of strings, etc.)
+and a function to compare the name returned by the ldap lookup with your
+group names.</UL>
+
+<CENTER><B><FONT SIZE=+1>Changes since Mar 22, 1997</FONT></B></CENTER>
+
+
+<P>Last Update: Apr 17, 1997
+
+<P>Now that all beta releases are out for servers using this library, I
+could do some incompatible changes to make this library more flexible.
+No more incompatible changes are planned (except for possibly one: see
+http://scopus/bugsplat/show_bug.cgi?id=58482). <B><BLINK>All 3.0 SuiteSpot
+servers supporting client auth need to upgrade to this version.</BLINK></B>
+<H2>
+Changed:</H2>
+
+<UL>
+<LI>
+<B>Exchanged certmap.h &amp; ldaputil.h: </B>ldaputil.h had public API
+but when the file was installed on the server root, it was called certmap.h.
+Since we already had a certmap.h, this was causing lot of confusion. If
+you were including "certmap.h", now include "ldaputil.h" and vice versa.</LI>
+
+<LI>
+<B>Renamed 'SearchComps' to 'FilterComps'</B>: Shouldn't affect your code
+but may affect tests and documentation.</LI>
+

+A query on how to map a verisign certificate prompted these changes.&nbsp;
+I was hoping I don't have to do any major changes when I wrote this document
+on Mar 18. These are incompatible changes -- please review them before
+you upgrade.&nbsp; I have checked in this file in CVS under "ns/netsite/lib/ldaputil/ldapu-changes.html".
+I have added all the "XYZ_branch" and "XYZ_point" tags to this file so
+that you can easily see this file in your tree.&nbsp; When I make significant
+changes to this file/library, I will retag this file for your branch to
+make it same as the server3_branch. [Let me know if I shouldn't do it for
+your branch].</DT>
+
+<H2>
+Changed:</H2>
+
+<UL>
+<LI>
+<B>ldapu_cert_to_ldap_entry</B>: The major change was to allow for the
+mapped DN to be NULL and in that case, start the search from the basedn
+of the LDAP server. This required API change so that the basedn can be
+passed to the ldapu_cert_to_ldap_entry function. This change was required
+for correctly mapping certs from verisign w/o writing plugins. The Verisign
+certs can be mapped correctly using the following setting in the &lt;ServerRoot>/userdb/certmap.conf
+file:</LI>
+
+<UL><TT><FONT SIZE=+1>certmap verisign &lt;verisign's DN></FONT></TT>
+<BR><TT><FONT SIZE=+1>verisign:dncomps</FONT></TT>
+<BR><TT><FONT SIZE=+1>verisign:searchcomps cn, e</FONT></TT></UL>
+The mapped DN will be NULL so basedn will be used.&nbsp; The filter will
+be
+<BR>(&amp; (cn="&lt;user's CN>") (mail="&lt;user's mail>")).&nbsp; The
+new signature of ldapu_cert_to_ldap_entry is as follows:
+<BR>&nbsp;&nbsp;&nbsp; int ldapu_cert_to_ldap_entry(void *cert, LDAP *ld,
+const char *basedn, LDAPMessage **res);
+<LI>
+<B>verify cert functions</B>: A major change in how verify cert functions
+work.&nbsp; This is function is now called even when multiple potential
+matches are found for the cert.&nbsp; The mapping is successful if the
+verify function can reduce the number of matches to exactly one.&nbsp;
+For example, if there are multiple "Joe Smith" entries, at most one of
+those will have the cert in it's "userCertificate" attr.&nbsp; The verify
+function will select that entry.&nbsp; The verify function is called with
+"LDAPMessage *res" containing all the potential matches.&nbsp; It should
+return a pointer to the matched entry in the new "LDAPMessage **entry"
+parameter.&nbsp; The new signature for CertVerifyFn_t is as follows:</LI>
+
+<BR>&nbsp;&nbsp;&nbsp; typedef int (*CertVerifyFn_t)(void *cert, LDAP *ld,
+LDAPMessage *res,
+<BR>&nbsp;
+
+<P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
+LDAPMessage **entry);
+<LI>
+typedef int (*<B>CertMapInitiFn_t)</B>: Renamed from CertmapInitFn_t.&nbsp;
+Now this has two extra parameters to make it easy to use it in a plugin.
+Other API functions require "issuerDN" but this function was called with
+"LDAPUCertMapInfo_t *certinfo".&nbsp; There was no public API function
+to get the issuerDN from "certinfo". The new signature for CertMapInitFn_t
+is as follows:</LI>
+
+<BR>&nbsp;&nbsp;&nbsp; typedef int (*CertMapInitFn_t)(void *certmap_info,
+const char *issuerName,
+<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
+const char *issuerDN);
+<LI>
+(ldapauth.h) <B>ldapu_auth_* functions:</B> For multiple matches, these
+functions now return LDAPU_ERR_MULTIPLE_MATCHES instead of LDAPU_FAILED.
+This change was required to make nested group membership work efficiently
+and enable the new functionality of verify cert function.</LI>

+
+<DT>
+There have been several changes to the netsite/lib/ldaputil recently. If
+you use this library, please start using the latest version of ldaputil
+on the server3_branch so that all the servers go out with the same API
+and behavior. Review the changes before you upgrade. If you don't plan
+to upgrade, please let me know.</DT>
+
+<H2>
+Renamed:</H2>

+The following changes may affect you. Please review them carefully before

+<UL>
+<LI>
+<TT>ldapu_auth_userdn_groupdn</TT> -- added <TT>const char *base</TT> argument
+for group within group membership check</LI>
+
+<LI>
+ldap_init and bind calls using <TT>LDAPDatabase_t *ldb</TT> retry once
+if the LDAP server is/went down.</LI>
+
+<LI>
+<TT>typedef CertVerifyFn_t</TT> has different arguments.</LI>
+
+<LI>
+DNs from cert with escaped/quoted characters are correctly handled now.</LI>
+
+<LI>
+cert to ldap entry mapping is optimized by not using string comparisons
+during thruntime. A bitmask is created when the config file is read, cert
+data is mapped to bits and compared against the bitmask.</LI>
+
+<LI>
+Only the required attrs are retrieved in most <TT>ldap_search_s </TT>calls
+from ldaputil. Some new functions were added to keep older functions the
+same.</LI>
+
+<LI>
+Fixed a core dump in ldapu_free_LDAPDatabase_t when using the local db.</LI>
+
+<LI>
+ldaputil functions for initializing connection to the LDAP server and binding
+to the server are thread-safe now. This requires linking to netsite/lib/base.
+If you don't use libbase, you can turn off the thread-safe code using a
+compile time option.</LI>
+</UL>
+
+<H2>
+Added:</H2>
+
+<UL>
+<LI>
+Documentation to functions in ldaputil.h (customer API) - ldaputil.h is
+the external public API for customers to write there plugins.</LI>
+
+<LI>
+<TT>ldapu_get_cert_der</TT> - returns raw DER encoded cert data</LI>
+
+<LI>
+<TT>ldapu_cert_to_user</TT> - Similar to ldapu_cert_to_ldap_entry but only
+retrieves the 'uid' and 'userCertificate' attributes from LDAP and also
+extracts the user id.</LI>
+
+<LI>
+<TT>ldapu_find_uid_attrs</TT> and <TT>ldapu_find_group_attrs</TT> - Similar
+to ldapu_find_uid and ldapu_find_group resp., but only retrieves the specified
+attributes. Internally used during password verification and group membership
+checks.</LI>
+
+<LI>
+<TT>ldapu_certinfo_delete, ldapu_certinfo_modify and ldapu_certinfo_save</TT>
+- API for the certmap config file GUI tool which is not yet developed.

+uniquemember attribute is not handled correctly in the group membership
+check. If the user's entry has 'x500UniqueIdentifier' attribute populated,
+the group could refer to the user entry by the user's dn followed by '#'
+and an unique identifier. For example, the group entry could have:</LI>
+
+<DD>
+uniquemember: cn=Joe Smith,o=Netscape,c=US#jsmith</DD>

+ * Description (aclAuthListParse)
+ *
+ *	This function parses an auth-list.  An auth-list specifies
+ *	combinations of user/group names and host addresses/names.
+ *	An auth-list entry can identify a collection of users and/or
+ *	groups, a collection of hosts by IP addresses or DNS names,
+ *	or a combination of the two.  Each auth-spec adds another
+ *	ACClients_t structure to the specified list.
+ *
+ *	The syntax for an auth-list is:
+ *
+ *	auth-list ::= auth-spec | auth-list "," auth-spec
+ *	auth-spec ::= auth-users [at-token auth-hosts]
+ *	auth-users - see aclAuthUsersParse()
+ *	auth-hosts - see aclAuthHostsParse()
+ *	at-token ::= "at" | "@"
+ *
+ *	The caller provides a pointer to a ClientSpec_t structure,
+ *	which is built up with new information as auth-specs are parsed.
+ *
+ * Arguments:
+ *
+ *	errp			- error frame list pointer (may be null)
+ *	acf			- pointer to ACLFile_t for ACL file
+ *	acc			- pointer to ACL context object
+ *	rlm			- pointer to authentication realm object
+ *	clsp			- pointer to returned ACClients_t list head
+ *
+ * Returns:
+ *
+ *	If successful, the return value is the token type of the token
+ *	following the auth-list, i.e. the first token which is not
+ *	recognized as the start of an auth-spec.  It is the caller's
+ *	responsibility to validate this token as a legitimate terminator
+ *	of an auth-list.  If a parsing error occurs in the middle of
+ *	an auth-spec, the return value is ACLERRPARSE, and an error frame
+ *	is generated if an error list is provided.  For other kinds of
+ *	errors a negative error code (from aclerror.h) is returned.

+ *	This provides access to a Netscape server database.
+ *	A server database is composed of two (libdbm) DB files.  One

+ * Description (ndbOpen)
+ *
+ *	This function opens a server database by name.  The specified
+ *	name may be the name of the primary DB file, or the name
+ *	without the ".db" suffix.  This function will attempt to open
+ *	both the primary and the id-to-name DB files for read access.
+ *	If either of the DB files do not exist, they are not created
+ *	here, but a handle for the database will still be returned.
+ *	The DB files will be created when a subsequent access writes
+ *	to the database.  The caller also specifies an application
+ *	database type, which is checked against a value stored in
+ *	in the database metadata, if the primary DB file exists, or
+ *	which is stored in the file metadata when the file is created.
+ *	A type-specific version number is passed and returned.  The
+ *	value passed will be stored in the file metadata if it is
+ *	subsequently created.  If the file exists, the value in the
+ *	file metadata is returned, and it is the caller's responsibility
+ *	to interpret it.
+ *
+ * Arguments:
+ *
+ *	errp			- error frame list pointer (may be null)
+ *	dbname			- primary DB filename
+ *	flags			- (currently unused - should be zero)
+ *	dbtype			- application DB type (NDB_TYPE_xxxxx)
+ *	version			- (in/out) type-specific version number
+ *
+ * Returns:
+ *
+ *	A handle that can be used for subsequent accesses to the database
+ *	is returned, or 0, if an error occurs, and an error frame is
+ *	generated if an error frame list was provided by the caller.

+ * o * matches anything
+ * o ? matches one character
+ * o \ will escape a special character
+ * o $ matches the end of the string
+ * o [abc] matches one occurence of a, b, or c. The only character that needs
+ *         to be escaped in this is ], all others are not special.
+ * o [a-z] matches any character between a and z
+ * o [^az] matches any character except a or z
+ * o ~ followed by another shell expression will remove any pattern
+ *     matching the shell expression from the match list
+ * o (foo|bar) will match either the substring foo, or the substring bar.
+ *             These can be shell expressions as well.
