* Fix an issue in ghost usersJan Zeleny2012-06-131-75/+47
| | | | | | | | | | | | | | | | | There was an issue with ghost members in nested groups. Consider a scenario with two groups A and B, B being member of A and having some ghost members. In such case SSSD stored both groups, then added membership between them and then added ghost members to the group B. The problem was that adding ghost members to group B didn't propagate these ghost members to group A. This functionality could have been solved by memberof plugin but the logic is far more complicated that changes this patch introduces. The change is simple: add ghost members at the same time as the group is created, even if groups are supposed to be stored in two passes. That way ghost members will be present at the time A -> B membership is created and they will be propagated as expected.
* LDAP: Auto-detect support for the ldap match ruleStephen Gallagher2012-06-136-5/+107
| | | | | | | | This patch extends the RootDSE lookup so that we will perform a second request to test whether the match rule syntax can be used. If both groups and initgroups are disabled in the configuration, this lookup request can be skipped.

* LDAP: Make sdap_initgr_common_store() non-staticStephen Gallagher2012-06-122-7/+15
| | | | | Move it to a private header so it can be reused by other initgroups C files.
* LDAP: Add helper function to get list of a user's groups from sysdbStephen Gallagher2012-06-122-33/+69

* LDAP: Fix incorrect switch statement in sdap_get_initgr_done()Stephen Gallagher2012-06-121-1/+1
| | | | | | | SDAP_SCHEMA_AD needs to be calling sdap_initgr_rfc2307bis_recv(), not sdap_initgr_nested_recv(). By coincidence both recv functions happened to be identical, but if one or the other changed, this would break unexpectedly.
* LDAP: Remove redundant checkStephen Gallagher2012-06-121-11/+0
| | | | | The same block appeared earlier in the function and neither variable could have changed values since.
* Utilize attribute exclusion in LDAP initgroupsJan Zeleny2012-05-311-3/+33
| | | | | | | | | | Previous patch added the possibility to exclude some attributes from a map when building an attribute list to be sent to server. The original reason for this functionality is the code handling LDAP initgroups. In this code, there is no need to fetch members of groups in question. This can save some performance since the list of members can be pretty long in some cases. This case apllies only to RFC2307 and generic RFC2307bis, it doesn't apply for IPA schema.
* Add support for filtering atributesJan Zeleny2012-05-3112-34/+58
| | | | | This patch adds support for filtering attributes when constructing attribute list from a map for LDAP query.

|
* Ghost members - removed sdap_check_aliases()Jan Zeleny2012-05-314-127/+0
| | | | | | | This function is no longer necessary because we don't have fake user entries any more. The original purpose of this function was to check if there are fake user entries for particular user and, if yes, to update its membership.
* Ghost members - support in LDAP providerJan Zeleny2012-05-311-186/+286
| | | | | | | | | | | | | | | | | | | | The original approach was to store name and original DN in an object in sysdb. When later referenced as member of a group, it was retrieved by its original DN and the correct information about its sysdb DN was stored in the group object which referenced it. The new approach doesn't use fake user objects, therefore this information has to be reached differently when constructing group memberships. The approach is to store all users to a hash table where original DN is used as the key and username as value. When constructing group memberships, the name is retrieved from this hash table instead of sysdb. This hash table is constructed when retrieving user objects from LDAP server - if the user is not present in sysdb, it is automatically stored in the hash table. Another situation is for rfc2307. Because there is no nesting there, we can construct the SYSDB_GHOST attribute directly and therefore don't need a hash table of ghost users.

* LDAP: Handle very large Active Directory groupsStephen Gallagher2012-05-105-45/+271
| | | | | | | | | | | | | Active Directory 2008R2 allows only 1500 group members to be retrieved in a single lookup. However, when we hit such a situation, we can take advantage of the ASQ lookups, which are not similarly limited. With this patch, we will add any members found by ASQ that were not found by the initial lookup so we will end with a complete group listing. https://fedorahosted.org/sssd/ticket/783
* LDAP: Add attr_count return value to build_attrs_from_map()Stephen Gallagher2012-05-1012-32/+54
| | | | | | | This is necessary because in several places in the code, we are appending to the attrs returned from this value, and if we relied on the map size macro, we would be appending after the NULL terminator if one or more attributes were defined as NULL.
* Try all KDCs when getting TGT for LDAPJakub Hrozek2012-05-091-15/+18
| | | | | | | | When the ldap child process is killed after a timeout, try the next KDC. When none of the ldap child processes succeed, just abort the connection because we wouldn't be able to authenticate to the LDAP server anyway. https://fedorahosted.org/sssd/ticket/1324
* Special-case LDAP_SIZELIMIT_EXCEEDEDJakub Hrozek2012-05-071-4/+9
| | | | | | | | | | | | Previous version of the SSSD did not abort the async LDAP search operation on errors. In cases where the request ended in progress, such as when the paging was very strictly limited, the old versions at least returned partial data. This patch special-cases the LDAP_SIZELIMIT_EXCEEDED error to avoid a user-visible regression. https://fedorahosted.org/sssd/ticket/1322
* Limit krb5_get_init_creds_keytab() to etypes in keytabStef Walter2012-05-071-0/+15
| | | | | | | | | * Load the enctypes for the keys in the keytab and pass them to krb5_get_init_creds_keytab(). * This fixes the problem where the server offers a enctype that krb5 supports, but we don't have a key for in the keytab. https://bugzilla.redhat.com/show_bug.cgi?id=811375
* If canon'ing principals, write ccache with updated default principalStef Walter2012-05-041-1/+2
| | | | | | | | | | | * When calling krb5_get_init_creds_keytab() with krb5_get_init_creds_opt_set_canonicalize() the credential principal can get updated. * Create the cache file with the correct default credential. * LDAP GSSAPI SASL would fail due to the mismatched credentials before this patch. https://bugzilla.redhat.com/show_bug.cgi?id=811518
* Modify behavior of pam_pwd_expiration_warningJan Zeleny2012-05-041-12/+30
| | | | | | | | | | | | | | | | | | New option pwd_expiration_warning is introduced which can be set per domain and can override the value specified by the original pam_pwd_expiration_warning. If the value of expiration warning is set to zero, the filter isn't apllied at all - if backend server returns the warning, it will be automatically displayed. Default value for Kerberos: 7 days Default value for LDAP: don't apply the filter Technical note: default value when creating the domain is -1. This is important so we can distinguish between "no value set" and 0. Without this possibility it would be impossible to set different values for LDAP and Kerberos provider.

| | | | | | | | If we get a user who is a member of a domain we haven't seen before, add a domain entry (auto-assigning its slice). Since we don't know the domain's real name, we'll just save the domain SID string as the name as well.
