2012-09-13FO: Check server validity before setting statusJakub Hrozek7-33/+49
The list of resolved servers is allocated on the back end context and kept in the fo_service structure. However, a single request often resolves a server and keeps a pointer until the end of a request and only then gives feedback about the server based on the request result. This presents a big race condition in case the SRV resolution is used. When there are requests coming in in parallel, it is possible that an incoming request will invalidate a server until another request that holds a pointer to the original server is able to give a feedback. This patch simply checks if a server is in the list of servers maintained by a service before reading its status. https://fedorahosted.org/sssd/ticket/1364
2012-09-12backend: initialize sudo only when it is enabled in servicesPavel Březina1-3/+63
https://fedorahosted.org/sssd/ticket/1458 When the responder is disabled and sudo_provider is set explicitly, a warning is print and the module will be initialized.

2012-09-12netgroup: resolve hostgroup membership correctlyPavel Březina1-1/+1
https://fedorahosted.org/sssd/ticket/1519 IPA host refactoring changed mapping of memberOf attribute which caused SSSD being unable to retrieve membership of hostgroup when being interpreted as netgroup.

https://fedorahosted.org/sssd/ticket/1516 If sysdb_set_user_attr failed, we would cancel the transaction, then go to the error handler and attempt to close it again.

2012-08-24Fix fallback in validate_tgt()Sumit Bose1-8/+20
To validate a TGT a keytab entry from the client realm is preferred but if none ca be found the last entry should be used. But the entry was freed and zeroed before it could be used. This should also fix the trusted domain use case mentioned in https://fedorahosted.org/sssd/ticket/1396 although a different approach then suggested in the ticket is used.

Removing bad examples of usage of sysdb_transaction_start/commit/end functions and making it more consistent (all files except of src/db/sysdb_*.c).

2012-08-23Clean up cache on server reinitializationPavel Březina5-4/+403
https://fedorahosted.org/sssd/ticket/734 We successfully detect when the server is reinitialized by testing the new lastUSN value. The maximum USN values are set to zero, but the current cache content remains. This patch removes records that were deleted from the server. It uses the following approach: 1. remove entryUSN attribute from all entries 2. run enumeration 3. remove records that doesn't have entryUSN attribute updated We don't need to do this for sudo rules, they will be refreshed automatically during next smart/full refresh, or when an expired rule is deleted.

https://bugzilla.redhat.com/show_bug.cgi?id=846664 If the first group was cached when processing the nested group membership, we would call tevent_req_done, effectivelly marking the whole nesting level as done.

2012-08-15FO: Return EAGAIN if there are more servers to tryJakub Hrozek1-0/+9
The caller should issue a next request, which would just shortcut with ENOENT.

2012-08-07Rename SYSDB_SUDO_CACHE_AT_OC to SYSDB_SUDO_CACHE_OCPavel Březina2-3/+3
It does not contain name of the object class attribute but the value itself. I renamed it to avoid confusion.
2012-08-07Subdomains: Send the DP reply in the correct formatJakub Hrozek1-14/+41
The DP was sending the reply in a format the responder did not expect, so the responder always failed to parse the message.
2012-08-07Failover: Return last tried server if it's still being triedJakub Hrozek1-2/+6
In the failover, we treat both KDC and LDAP on the IPA server as a single "port", numbered 0. This was done in order to make sure that the SSSD always talks to the same server for both LDAP and Kerberos. However, this clever hack breaks when the IPA provider needs to establish an GSSAPI encrypted LDAP connection because we're asking the fail over code to yield a server while no server has yet been marked as tried. This triggers a fail over for the KDC, so in effect, the TGT is received from second server. If the second server is not available for some reason, the whole provider goes offline. The fail over needs to detect that the server asked for is still being resolved and return the same pointer.

This bug was producing harmless, but annoying error messages.
2012-08-01Create a domain-realm mapping for krb5.conf to be includedJakub Hrozek1-0/+135
When new subdomains are discovered, the SSSD creates a file that includes the domain-realm mappings. This file can in turn be included in the krb5.conf using the includedir directive, such as: includedir /var/lib/sss/pubconf/realm_mappings

2012-08-01Change refreshing of subdomainsSimo Sorce3-67/+156
This patch keeps a local copy of the subdomains in the ipa subdomains plugin context. This has 2 advantages: 1. allows to check if anything changed w/o always hitting the sysdb. 2. later will allows us to dump this information w/o having to retrieve it again. The timestamp also allows to avoid refreshing too often.
2012-08-01Expose an initializer function from subdomainSimo Sorce3-32/+46
Instead of exporting internal structures, expose an initilizer function like the autofs code and initialize everything inside the ipa_subdomains.c file.
2012-08-01Add realm paramter to subdomain listSimo Sorce1-0/+27
This will be used later for setting domain_realm mappings in krb5.conf

I am all for readable names, but there is a tradeof between expressing purpose and compactness.
2012-08-0180 col and style fixesSimo Sorce1-20/+48
Something like this: sysdb = (be_req->sysdb)?be_req->sysdb:be_req->be_ctx->sysdb; really is not readable, and we always discourage using obfuscated C, please refrain in future.
