* Removing unused declaration of functions and variable.Lukas Slebodnik2013-03-191-2/+2
| | | | | | Variables dir_cc and file_cc are used in three modules: krb5_common.c, krb5_utils.c, krb5_child-test.c, therefore should be declared with extern in krb5_utils.h.
* Decrease krb5_auth_timeout defaultOndrej Kos2013-03-181-1/+1
| | | | https://fedorahosted.org/sssd/ticket/1738
* Retry the correct service on krb5 child timeoutJakub Hrozek2013-03-181-1/+1

* More generalized function open_debug_file_ex()Lukas Slebodnik2013-03-131-5/+1
| | | | | | | | Function open_debug_file_ex() set flag FD_CLOEXEC to opened file according to the value of third parameter. Removed duplicity of unsetting FD_CLOEXEC after calling function open_debug_file_ex()
* Add support for krb5 1.11's responder callback.Nathaniel McCallum2013-03-084-1/+232
| | | | | | | | | | | krb5 1.11 adds support for a new method for responding to structured data queries. This method, called the responder, provides an alternative to the prompter interface. This patch adds support for this method. It takes the password and provides it via a responder instead of the prompter. In the case of OTP authentication, it also disables the caching of credentials (since the credentials are one-time only).
* Cleanup error message handling for krb5 childSimo Sorce2013-03-042-296/+240
| | | | | | | | | | | | | | | | | | | | Use the new internal SSSD errors, to simplify error handling. Instead of using up to 3 different error types (system, krb5 and pam_status), collapse all error reporting into one error type mapped on errno_t. The returned error can contain either SSSD internal errors, kerberos errors or system errors, they all use different number spaces so there is no overlap and they can be safely merged. This means that errors being sent from the child to the parent are not pam status error messages anymore. The callers have been changed to properly deal with that. Also note that this patch removes returning SSS_PAM_SYSTEM_INFO from the krb5_child for kerberos errors as all it was doing was simply to make the parent emit the same debug log already emitted by the child, and the code is simpler if we do not do that.
* krb5_child: fix value type and initializationOndrej Kos2013-03-041-1/+2
| | | | ret was defined as integer, instead of errno_t, and was uninitialized
* Refactor krb5 childSimo Sorce2013-02-281-288/+210
| | | | | | | | | | | | | | | | | | | | | | | | | | The aim of this refactoring is to make the code readable and understandable. This code has grown organically over time and has becomed confused and baroque enough that understanding it's very simple flow had become very complex for the uninitiated. Complex flows easily hide nasty bugs. Improvements: - Remove dead/unused data storage - Fix and simplify talloc hierarchy, use a memory context (kr) for the whole code and allocate kr->pd where it is filled up. - Rename some functions to create a better name space (easier for searching fucntions across the tree) - Streamline setup function, by spliting out fast setup in a subroutine. - Avoid confusing indirection in executng actual functions by not using the krb5_req child_req member. - Make main() flow s now simmetric, send abck data from the main function instead of delegating a reply to every inner function that implements a command. Now the flow is evident from the main function: 1. read request 2. setup data 3. execute command 4. send reply back
* krb5_child style fixSimo Sorce2013-02-281-11/+11
| | | | Use the standard 'done' label for exceptions.
* Do not process success case in an elseJakub Hrozek2013-02-261-24/+24

* krb: recreate ccache if it was deletedPavel Březina2013-01-301-1/+8
| | | | | | | | | https://fedorahosted.org/sssd/ticket/1512 If directory where a ccache file was stored was missing and user was still logged in, we erroneously considered the ccache file still active. Thus the ccache file was not recreated and user was unable to login.
* Add be_req_get_data() helper funciton.Simo Sorce2013-01-211-4/+4
| | | | In preparation for making struct be_req opaque.
* Add be_req_get_be_ctx() helper.Simo Sorce2013-01-212-10/+12
| | | | In preparation for making be_req opaque
* Introduce be_req_terminate() helperSimo Sorce2013-01-211-10/+3
| | | | | Call it everywhere instead of directly dereferencing be_req->fn This is in preparation of making be_req opaque.
* Remove sysdb as a be context structure memberSimo Sorce2013-01-213-5/+5
| | | | The sysdb context is already available through the 'domain' structure.
* Add domain argument to sysdb_cache_auth()Simo Sorce2013-01-151-1/+5
|
* Add domain argument to sysdb_cache_password()Simo Sorce2013-01-151-3/+5
|
* Add domain argument to sysdb_set_user_attr()Simo Sorce2013-01-151-5/+8
|
* Add domain argument to sysdb_get_user_attr()Simo Sorce2013-01-154-10/+12
|
* Change pam data auth tokens.Simo Sorce2013-01-105-147/+186
| | | | Use the new authtok abstraction and interfaces throught the code.
* Code can only check for cached passwordsSimo Sorce2013-01-101-4/+17
| | | | | Make it clear to the API users that we can not take arbitrary auth tokens. We can only take a password for now so simplify and clarify the interface.
* let krb5_backup_kpasswd failover workPavel Březina2013-01-021-2/+2
| | | | https://fedorahosted.org/sssd/ticket/1735
* failover: Protect against empty host namesMichal Zidek2013-01-021-1/+1
| | | | | | | | | | Added new parameter to split_on_separator that allows to skip empty values. The whole function was rewritten. Unit test case was added to check the new implementation. https://fedorahosted.org/sssd/ticket/1484
* krb5 tgt renewal: fix usage of ldb_dn_get_component_val()Sumit Bose2012-12-201-4/+4
| | | | | For some reason I was under the impression that the DN components are counted backwards in libldb. This patch corrects this.
* let krb5_kpasswd failover workPavel Březina2012-12-101-3/+7
| | | | | | | | | https://fedorahosted.org/sssd/ticket/1680 There were two errors: 1. kr->kpasswd_srv was never set 2. bad service name (KERBEROS) was provided when setting port status, thus the port status never changed
* Fix tevent_req style for krb5_authSimo Sorce2012-12-044-371/+334
| | | | | | No functionality changes, just make the code respect the tevent_req style and naming conventions and enhance readability by adding some helper functions.
* Save errno before it might be modified.Simo Sorce2012-11-261-8/+16
| | | | | The DEBUG() macro may, at any time, change and start calling functions that touch errno. Save errno before logging and then return the saved error.
* Disable canonicalization during password changesSumit Bose2012-11-191-2/+43
| | | | | | | | | | | | | | | If canonicalization is enabled Active Directory KDCs return 'krbtgt/AD.DOMAIN' as service name instead of the expected 'kadmin/changepw' which causes a 'KDC reply did not match expectations' error. Additionally the forwardable and proxiable flags are disabled, the renewable lifetime is set to 0 and the lifetime of the ticket is set to 5 minutes as recommended in https://fedorahosted.org/sssd/ticket/1405 and also done by the kpasswd utility. Fixes: https://fedorahosted.org/sssd/ticket/1405 https://fedorahosted.org/sssd/ticket/1615
* Fix compare_principal_realm() checkSumit Bose2012-11-191-9/+3
| | | | | In case of a short UPN compare_principal_realm() erroneously returns an error.
* Just use the service name with krb5_get_init_creds_password()Sumit Bose2012-11-191-24/+2
| | | | | | | | | Currently we add the realm name to change password principal but according to the MIT Kerberos docs and the upstream usage the realm name is just ignored. Dropping the realm name also does not lead to confusion if the change password request was received for a user of a trusted domain.
* Only build extract_and_send_pac on platforms that support itJakub Hrozek2012-11-121-104/+18

* KRB5: Rename variable to avoid shadowing a global declarationJakub Hrozek2012-11-121-4/+4
| | | | | | | src/providers/krb5/krb5_utils.c: In function ‘cc_dir_create’: src/providers/krb5/krb5_utils.c:824: warning: declaration of ‘dirname’ shadows a global declaration /usr/include/libgen.h:27: warning: shadowed declaration is here
* Do not always return PAM_SYSTEM_ERR when offline krb5 authentication failsJakub Hrozek2012-11-121-1/+2

* Include talloc log in our debug facilityMichal Zidek2012-10-291-1/+1
| | | | https://fedorahosted.org/sssd/ticket/1495
* krb5_auth: update with correct UPN if neededSumit Bose2012-10-263-0/+133
| | | | | | | | | The Active Directory KDC handles request case in-sensitive and it might not always to possible to guess the UPN with the correct case. We check if the returned principal has a different case then the one used in the request and updates the principal if needed. This will help using calls from the Kerberos client libraries later on which would otherwise fail because the principal is handled case sensitive by those libraries.
* Use find_or_guess_upn() where neededSumit Bose2012-10-264-34/+49
|
* Add new call find_or_guess_upn()Sumit Bose2012-10-264-8/+54
| | | | | | | | | With the current approach the upn was either a pointer to a const string in a ldb_message or a string created with the help of talloc. This new function always makes it a talloc'ed value. Additionally krb5_get_simple_upn() is enhanced to handle sub-domains as well.
* krb5_child: send back the client principalSumit Bose2012-10-263-5/+41
| | | | | | | | | | | | | In general Kerberos is case sensitive but the KDC of Active Directory typically handles request case in-sensitive. In the case where we guess a user principal by combining the user name and the realm and are not sure about the cases of the letters used in the user name we might get a valid ticket from the AD KDC but are not able to access it with the Kerberos client library because we assume a wrong case. The client principal in the returned credentials will always have the right cases. To be able to update the cache user principal name the krb5_child will return the principal for further processing.
* krb5_mod_ccname: replace wrong memory contextSumit Bose2012-10-261-1/+1
|
* krb5_child: send PAC to PAC responderSumit Bose2012-10-261-1/+139
| | | | | | If the authenticated user comes from a different realm the service ticket which was returned during the validation of the TGT is used to extract the PAC which is send to the pac responder for evaluation.
* krb5_auth: send different_realm flag to krb5_childSumit Bose2012-10-262-1/+8
| | | | | | | The different_realm flag which was set by the responder is send to the krb5_child so that it can act differently on users from other realms. To avoid code duplication and inconsistent behaviour the krb5_child will not set the flag on its own but use the one from the provider.
* krb5_auth: check if principal belongs to a different realmSumit Bose2012-10-264-0/+43
| | | | | | Add a flag if the principal used for authentication does not belong to our realm. This can be used to act differently for users from other realms.
* check_ccache_files: search sub-domains as wellSumit Bose2012-10-261-4/+14
| | | | | If sssd is configured to renew Kerberos tickets automatically ticket of sub-domain uses should be renewed as well.
* krb5_auth_send: check for sub-domainsSumit Bose2012-10-263-5/+37
| | | | | | If there is an authentication request for a user from a sub-domain a temporary sysdb context is generated to allow lookups in the corresponding sub-tree in the cache.
* Only call krb5_set_trace_callback on platforms that support itJakub Hrozek2012-10-121-1/+1
|
* Collect krb5 trace on high debug levelsJakub Hrozek2012-10-122-2/+25
| | | | | | | If the debug level contains SSSDBG_TRACE_ALL, then the logs would also include tracing information from libkrb5. https://fedorahosted.org/sssd/ticket/1539
* Two fixes to child processesJakub Hrozek2012-10-121-2/+0
| | | | | | | | There was an unused structure member in the krb5_child. Declaration of __krb5_error_msg was shadowing the same variable from sss_krb5.h which is not nice. Also we might actually use the error context directly instead of passing it as parameter.
