2012-05-31Ghost members - sysdb upgrade routineJan Zeleny3-1/+157
It is remotely possible to have sysdb in an inconsistent state that might need upgrade. Consider scenario when user asks for group information. Some fake users are added as a part of this operation. Before users can be fully resolved and stored properly, SSSD is shut down and upgrade is performed. In this case we need to go over all fake user records (uidNumber=0) and replace each of them with ghost record in all group objects that are stated in its memberof attribute.

2012-05-31Ghost members - modifications in sysdbJan Zeleny2-80/+153
Deleted sysdb_add_fake_user(): This function is no longer used. Modified sysdb_add_user(): When user object is added to sysdb, it is important to iterate over all groups that might have its name or any of its aliases as ghost member and replace this ghost membership by a real one. This will eliminate duplicite memberships.

2012-05-31Ghost members - support in LDAP providerJan Zeleny1-186/+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.

There was an issue when IPA provider didn't set PAM_SUCCESS when successfully finished loading SELinux user maps. This lead to the map not being read in the responder.

2012-05-16NSS: Expire in-memory netgroup cache before the nowait timeoutStephen Gallagher1-1/+9
The fact that we were keeping it in memory for the full duration of the cache timeout meant that we would never reap the benefits of the midpoint cache refresh. https://fedorahosted.org/sssd/ticket/1340

2012-05-11SYSDB: Handle user and group renames betterJakub Hrozek2-7/+182
Fixes a regression in the local domain tools where sss_groupadd no longer detected a GID duplicate. The check for EEXIST is moved one level up into more high level function. The patch also adds the same rename support for users. I found it odd that we allowed a rename of groups but not users. There is a catch when storing a user -- his cached password would be gone. I think that renaming a user is such a rare operation that it's not severe, plus there is a warning in the logs.

2012-05-10LDAP: Handle very large Active Directory groupsStephen Gallagher5-45/+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
2012-05-10LDAP: Add attr_count return value to build_attrs_from_map()Stephen Gallagher17-39/+62
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.

2012-05-09NSS: Add fallback_homedir optionStephen Gallagher9-6/+68
This option is similar to override_homedir, except that it will take effect only for users that do not have an explicit home directory specified in LDAP. https://fedorahosted.org/sssd/ticket/1250
2012-05-09Try all KDCs when getting TGT for LDAPJakub Hrozek1-15/+18

2012-05-07Special-case LDAP_SIZELIMIT_EXCEEDEDJakub Hrozek1-4/+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

* 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

2012-05-04SSSDConfigAPI: Fix missing option in testsStephen Gallagher1-0/+2
2012-05-04Modify behavior of pam_pwd_expiration_warningJan Zeleny9-52/+119
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.
2012-05-04Fix endian issue in SID conversionSumit Bose3-10/+18
Since the byte-order is only important when dealing with the binary SID the sub-auth values are stored in host order and are only converted while reading or writing the binary SID.
