2013-03-18Retry the correct service on krb5 child timeoutJakub Hrozek1-1/+1
2013-03-13Fix initialization of multiple variablesOndrej Kos2-4/+3
2013-03-13More generalized function open_debug_file_ex()Lukas Slebodnik1-5/+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()
2013-03-08Add support for krb5 1.11's responder callback.Nathaniel McCallum4-1/+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).
2013-03-04Cleanup error message handling for krb5 childSimo Sorce2-296/+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.
2013-03-04krb5_child: fix value type and initializationOndrej Kos1-1/+2
ret was defined as integer, instead of errno_t, and was uninitialized
2013-02-28Refactor krb5 childSimo Sorce1-288/+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
2013-02-28krb5_child style fixSimo Sorce1-11/+11
Use the standard 'done' label for exceptions.

2013-02-10Add realm info to sss_domain_infoSimo Sorce1-1/+2
2013-01-30Fix minor grammar error in logStephen Gallagher1-1/+1
2013-01-30krb: recreate ccache if it was deletedPavel Březina1-1/+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.
2013-01-21Add be_req_get_data() helper funciton.Simo Sorce1-4/+4
In preparation for making struct be_req opaque.
2013-01-21Add be_req_get_be_ctx() helper.Simo Sorce2-10/+12
In preparation for making be_req opaque
2013-01-21Introduce be_req_terminate() helperSimo Sorce1-10/+3
Call it everywhere instead of directly dereferencing be_req->fn This is in preparation of making be_req opaque.
2013-01-21Remove sysdb as a be context structure memberSimo Sorce3-5/+5
The sysdb context is already available through the 'domain' structure.
2013-01-15Add domain argument to sysdb_cache_auth()Simo Sorce1-1/+5
2013-01-15Add domain argument to sysdb_cache_password()Simo Sorce1-3/+5
2013-01-15Add domain argument to sysdb_set_user_attr()Simo Sorce1-5/+8
2013-01-15Add domain argument to sysdb_get_user_attr()Simo Sorce4-10/+12
2013-01-10Change pam data auth tokens.Simo Sorce5-147/+186
Use the new authtok abstraction and interfaces throught the code.
2013-01-10Code can only check for cached passwordsSimo Sorce1-4/+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.
2013-01-02let krb5_backup_kpasswd failover workPavel Březina1-2/+2
https://fedorahosted.org/sssd/ticket/1735
2013-01-02failover: Protect against empty host namesMichal Zidek1-1/+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
2012-12-20krb5 tgt renewal: fix usage of ldb_dn_get_component_val()Sumit Bose1-4/+4
For some reason I was under the impression that the DN components are counted backwards in libldb. This patch corrects this.
2012-12-10let krb5_kpasswd failover workPavel Březina1-3/+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
2012-12-04Fix tevent_req style for krb5_authSimo Sorce4-371/+334
No functionality changes, just make the code respect the tevent_req style and naming conventions and enhance readability by adding some helper functions.
2012-11-26Save errno before it might be modified.Simo Sorce1-8/+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.
2012-11-19Disable canonicalization during password changesSumit Bose1-2/+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
2012-11-19Fix compare_principal_realm() checkSumit Bose1-9/+3
In case of a short UPN compare_principal_realm() erroneously returns an error.
2012-11-19Just use the service name with krb5_get_init_creds_password()Sumit Bose1-24/+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.
2012-11-12Only build extract_and_send_pac on platforms that support itJakub Hrozek1-104/+18
2012-11-12KRB5: Rename variable to avoid shadowing a global declarationJakub Hrozek1-4/+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
2012-11-12Do not always return PAM_SYSTEM_ERR when offline krb5 authentication failsJakub Hrozek1-1/+2

2012-10-26krb5_auth: update with correct UPN if neededSumit Bose3-0/+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.
2012-10-26Use find_or_guess_upn() where neededSumit Bose4-34/+49
2012-10-26Add new call find_or_guess_upn()Sumit Bose4-8/+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.
2012-10-26krb5_child: send back the client principalSumit Bose3-5/+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.
2012-10-26krb5_mod_ccname: replace wrong memory contextSumit Bose1-1/+1
2012-10-26krb5_child: send PAC to PAC responderSumit Bose1-1/+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.
2012-10-26krb5_auth: send different_realm flag to krb5_childSumit Bose2-1/+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.
2012-10-26krb5_auth: check if principal belongs to a different realmSumit Bose4-0/+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.
2012-10-26check_ccache_files: search sub-domains as wellSumit Bose1-4/+14
If sssd is configured to renew Kerberos tickets automatically ticket of sub-domain uses should be renewed as well.
2012-10-26krb5_auth_send: check for sub-domainsSumit Bose3-5/+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.
2012-10-12Only call krb5_set_trace_callback on platforms that support itJakub Hrozek1-1/+1
2012-10-12Collect krb5 trace on high debug levelsJakub Hrozek2-2/+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
2012-10-12Two fixes to child processesJakub Hrozek1-2/+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.
2012-10-10Add more info about ticket validationOndrej Kos1-0/+8
https://fedorahosted.org/sssd/ticket/1499 Adds log message about not finding appropriate entry in keytab and using the last keytab entry when validation is enabled. Adds more information about validation into manpage.
2012-10-04Log possibly non-randomizable ccache file templateOndrej Kos4-6/+26
fixes https://fedorahosted.org/sssd/ticket/1533 ccache file template is now checked for appended XXXXXX for use with mkstemp. When those characters are not present, warning is written to log.
