2013-08-26PAC: use SID instead of GID to search for groupsSumit Bose1-48/+41
With the support of POSIX IDs managed on the AD side we may find non-POSIX groups, i.e. groups which do not have a GID assigned in AD, in the PAC. Since in this case all cached groups have a SDI attribute it is more reliable to search the groups by SID instead of GID.
2013-08-26PAC: do not fail if a single group cannot be added/removedSumit Bose1-18/+31
When processing a list of groups we try to process as much as possible only not stop on the first error.
2013-08-26PAC: read user DN instead of constructing itSumit Bose1-5/+17
To avoid issues with case-sensitivity it is more reliable to search the user entry in the cache and use the returned DN instead of constructing it.
2013-08-26PAC: handle non-POSIX groups in cacheSumit Bose2-11/+9
Since the DN of the group is used to remove a membership it is not necessary to check if the GID is valid.
2013-08-26PAC: do not create users with missing GIDSumit Bose1-0/+14
If the user entry does not exist in the cache and a primary GID cannot be found it does not make sense to create a user entry.
2013-08-26PAC: if user entry already exists keep itSumit Bose3-86/+10
Currently the PAC responder deletes a user entry and recreates it if some attributes seems to be different. Two of the attributes where the home directory and the shell of the user. Those two attributes are not available from the PAC but where generates by the PAC responder. The corresponding ID provider might have better means to determine those attributes, e.g. read them from LDAP, so we shouldn't change them here. The third attribute is the user name. Since the PAC responder does lookups only based on the UID we can wait until the ID provider updates the entry. Fixes https://fedorahosted.org/sssd/ticket/1996
2013-08-22pam: Bad debug message format and parameter.Michal Zidek1-1/+2
2013-08-22mmap_cache: Use sss_atomic_write_s instead of write.Michal Zidek1-2/+11
Use sss_atomic_write_s() instead of write() in sss_mc_save_corrupted(). Also unlink() the file if no data were written. It is better to use sss_atomic_write_s instead of write
2013-08-19mmap_cache: Store corrupted mmap cache before resetMichal Zidek1-0/+66
This patch adds function to store corrupted mmap cache file to disk for further analysis.
2013-08-19mmap_cache: Use better checks for corrupted mc in responderMichal Zidek1-3/+53
We introduced new way to check integrity of memcache in the client code. We should use similiar checks in the responder.
2013-08-19mmap_cache: Off by one error.Michal Zidek1-6/+6
Removes off by one error when using macro MC_SIZE_TO_SLOTS and adds new macro MC_SLOT_WITHIN_BOUNDS.
2013-08-19fill_initgr: add original primary GID if availableSumit Bose1-0/+27
In some cases when MPG domains are used the information about the original primary group of a user cannot be determined by looking at the explicit group memberships. In those cases the GID related to the original primary group is stored in a special attribute of the user object. This patch adds the GID of the original primary group when available and needed. Fixes https://fedorahosted.org/sssd/ticket/2027
2013-08-11mmap_cache: Check if slot and name_ptr are not invalid.Michal Zidek2-2/+54
This patch prevents jumping outside of allocated memory in case of corrupted slot or name_ptr values. It is not proper solution, just hotfix until we find out what is the root cause of ticket https://fedorahosted.org/sssd/ticket/2018
2013-08-08PAM: Set negcache if user is not found after provider checkJakub Hrozek1-0/+10
2013-08-08PAM: Check negcache when searching for fully qualified users, tooJakub Hrozek1-0/+8
2013-08-08NSS: Clear cached netgroups if a request comes in from the sss_cacheLukas Slebodnik3-0/+54
In order for sss_cache to work correctly, we must also signal the nss responder to invalidate the hash table requests. https://fedorahosted.org/sssd/ticket/1759
2013-08-08NSS: allow removing entries from netgroup hash tableLukas Slebodnik3-1/+32
There is a timed desctructor in the nss responder that, when the entry timeout passes, removes the netgroup from the hash table while the netgroup is freed. This patch adds a hash delete callback so that if the netgroup is removed from the hash table with hash_delete, its hash table pointer will be invalidated. Later, when the entry is being freed, the destructor won't attempt to remove it from the hash table.
2013-08-05SSH: Ensure that cmd_ctx->name will not be NULL.Lukas Slebodnik1-4/+6
If cmd_ctx->name was not initialized by sss_parse_name then copy of name will be used. https://fedorahosted.org/sssd/ticket/1970 Coverity ID: 11647
2013-07-31Fix netgroup lookup when using fully qualified namePavel Březina1-2/+2
2013-07-29Netgroups should ignore the 'use_fully_qualified_names' settingStephen Gallagher1-8/+6
Netgroups often have memberNisNetgroup entries included in them that will never process correctly if we require fully-qualified names on the nested lookup. This patch alters the behavior of netgroup lookups to check *all* domains for an unqualified netgroup name, instead of only the ones not requiring fully- qualified names. https://fedorahosted.org/sssd/ticket/2013
2013-07-29Remove unused memory contextLukas Slebodnik1-6/+6
2013-07-22SUDO: realloc with sizeof(uint32_t) when adding uint32_tJakub Hrozek1-1/+1
2013-07-18Do not try to set password when authtok_length is zeroOndrej Kos1-2/+6
https://fedorahosted.org/sssd/ticket/1814 When the authtok_length is zero, it shouldn't call sss_authtok_set_password, because it tries to determine lenght of passed string by itself and would read parts of DBus message behind boundaries of authtok.
2013-07-16remove unused variablePavel Březina1-4/+0
2013-07-16Remove unused function parameterLukas Slebodnik1-3/+1
2013-07-15Missing space in debug messageMichal Zidek1-2/+2
2013-06-27Do not call sss_cmd_done in function check_cache.Lukas Slebodnik1-6/+0
Function sysdb_getpwnam return more results than 1 and therefore sss_cmd_done was called. Inside of function sss_cmd_done memory was freed, but this freed memory was used in caller functions, therefore sssd crashed. https://fedorahosted.org/sssd/ticket/1980
2013-06-27Handle too many results from getnetgr.Lukas Slebodnik1-1/+13
2013-06-27SSH: Update known_hosts file after unsuccessful requests as well.Jan Cholasta1-20/+36
https://fedorahosted.org/sssd/ticket/1949
2013-06-27sudo responder: use different callback for oob refreshPavel Březina1-6/+8
https://fedorahosted.org/sssd/ticket/1693 Since we don't care about returned values from out of band refresh, we do not need to set callback data. However, this caused talloc to abort as it considers it as type mismatch when called from tevent_req_callback_data().
2013-06-24PAC: do not delete originalDN or cached password if presentSumit Bose1-1/+26
If the PAC responder recognizes some attribute changes between the cached user entry and the PAC data it quite crudely just removes the cached entry and recreates it. While in most cases all needed data can be recovered from the PAC data there is a case where it is not possible. E.g the IPA HBAC code use the OriginalDN attribute to improve performance when evaluating access rules. This patch makes sure this attribute is not lost when the PAC responder updates the object.
2013-06-19PAC: do not expect that sysdb_search_object_by_sid() return ENOENTSumit Bose1-8/+8
sysdb_search_object_by_sid() does not return ENOENT if no related object was found in the cache but EOK and an empty result list. Fixes https://fedorahosted.org/sssd/ticket/1989
2013-06-07New utility function sss_get_domain_nameJakub Hrozek2-19/+10
Instead of copying a block of code that checks whether domain is a subdomain and uses only name of FQDN as appropriate, wrap the logic into a function.
2013-06-06Enhance PAC responder for AD usersSumit Bose3-927/+659
This patch modifies the PAC responder so that it can be used with the AD provider as well. The main difference is that the POSIX UIDs and GIDs are now lookup up with the help of the SID instead of being calculated algorithmically. This was necessary because the AD provider allows either algorithmic mapping or reading the value from attributes stored in AD. Fixes https://fedorahosted.org/sssd/ticket/1558
2013-06-04Lookup domains at startupSumit Bose8-0/+89
To make sure that e.g. the short/NetBIOS domain name is available this patch make sure that the responders send a get_domains request to their backends at startup the collect the domain information or read it from the cache if the backend is offline. For completeness I added this to all responders even if they do not need the information at the moment. Fixes https://fedorahosted.org/sssd/ticket/1951
2013-05-30Remove branching to improve readabilityJakub Hrozek1-23/+11
2013-05-30Allow flat name in the FQname formatJakub Hrozek1-3/+3
https://fedorahosted.org/sssd/ticket/1648 Adds another expansion in the printf format that allows the user to use the domain flat name in the format.
2013-05-30Add utility functions for formatting fully-qualified namesJakub Hrozek3-34/+22
Instead of using printf-like functions directly, provide two wrappers that would encapsulate formatting the fully-qualified names. No functional change is present in this patch.
2013-05-20Fixing critical format string issues.Lukas Slebodnik7-14/+25
--missing arguments. --format '%s', but argument is integer. --wrong format string, examle: '%\n'
2013-05-10sudo responder: search rules for subdomains in parent domain subtreePavel Březina1-0/+5
https://fedorahosted.org/sssd/ticket/1912 SUDO rules are stored under cn=ipa.domain,cn=sysdb tree but sobdomains users are in cn=sub.domain,cn=sysdb. When we search for rules for subdomain users we have to switch domain context to parent.
2013-05-10Add missing \n to debug stringSumit Bose1-1/+1
2013-05-07SSH: Do not skip domains with use_fully_qualified_names in host key requestsJan Cholasta1-6/+0
2013-05-07SSH: Use separate field for domain name in client requestsJan Cholasta1-27/+64
Instead of appending @domain to names when the --domain option of sss_ssh_* is used, put domain name in a separate field in client requests.
2013-05-07SSH: Fix parsing of names from client requestsJan Cholasta3-3/+30
Try to parse names in the form user@domain first, as that's what sss_ssh_* send in requests when the --domain option is used. Do not parse host names using domain-specific regular expression.
2013-05-03Add SID related calls to the NSS responderSumit Bose2-3/+795
The patch adds 4 new calls to the NSS responder: - SSS_NSS_GETSIDBYNAME - SSS_NSS_GETSIDBYID - SSS_NSS_GETNAMEBYSID - SSS_NSS_GETIDBYSID to either return the SIDs of the requested object or map the SID to the name or the POSIX ID of the related object.
2013-05-02Add sss_ncache_set_sid() and sss_ncache_check_sid()Sumit Bose2-0/+31
Two new calls are added to allow to add SID based lookups to the negative cache.
2013-05-02Add responder_get_domain_by_id()Sumit Bose2-0/+52
This new call is similar to responder_get_domain() but uses the domain SID as search parameter. Since the length of the stored domain SID is used in the comparison, SIDs of users and groups and be used directly without stripping the RID component. The functionality is not merged into responder_get_domain() to allow to calculate the timeout correctly and return a specific error code if the entry is expired.
2013-05-02Add idmap context to nss contextSumit Bose2-0/+22
This allows the nss responder to use libsss_idmap to convert between different SID representations.
2013-05-02Add two new request types to the data-provider interfaceSumit Bose2-1/+9
The patch adds two new request types for SID related requests. The first one is used if a SID is given and the corresponding object should be found. The second one can be used if the SID for an object is requested but it is not clear if the object is a user or a group.
2013-05-02Add secid filter to responder-dp protocolSumit Bose1-4/+14
This patch add a new filter type to the data-provider interface which can be used for SID-based lookups.
