2012-12-18select_principal_from_keytab() do wildcard lookups after specific onesSumit Bose1-3/+3
Currently the wildcard lookup '*$' is done before the one for host/our.hostname@REALM. This means we would ignore a more specific match in favour of an unspecific match with a principal which is only used in a AD environment. I think this is wrong an wildcards should only be used is all specific lookups fail.
2012-12-18select_principal_from_keytab() look for plain input as wellSumit Bose1-2/+6
Currently in select_principal_from_keytab() all kind of different versions of the host principal are looked up in the keytab except for the plain name the ldap_sasl_authid option. With this patch the plain name is looked up first.
2012-12-18Set cloexec flag for log filesJakub Hrozek1-0/+11
https://fedorahosted.org/sssd/ticket/1708 The services kept the fd to /var/log/sssd/sssd.log open. I don't think there's any point in keeping the logfiles open after exec-ing for the child, so I set the CLOEXEC flag.
2012-11-28Avoid const warnings when deallocating memorySimo Sorce1-1/+1
In some case we allocate and assign data to a const pointer. When we then try to free it we would get a const warning because talloc_free accepts a void, not a const void pointer. Use discard_const to avoid the warning, it is safe in this case.
2012-11-28Revert "Avoid accessing half-deallocated memory when using talloc_zfree macro."Simo Sorce1-5/+1
This reverts commit ff57c6aeb80a52b1f52bd1dac9308a69dc7a4774. This commit doesn't really make sense, we are never accessing freed memory as all we are dealing with is a pointer which is never itsef part of the memory we are freeing (if it were, it would be an error in the caller and we shouldn't mask it in this macro).
2012-11-26debug: print fatal and critical errors if debug level is unresolvedMichal Zidek1-1/+4
If global variable debug_level has value SSSDBG_UNRESOLVED, we should print at least fatal and critical errors. https://fedorahosted.org/sssd/ticket/1345

2012-11-21MONITOR: Fix off-by-one error in add_string_to_listJakub Hrozek1-1/+4
We need to allocate num_services+2 - one extra space for the new service and one for NULL.
2012-11-19Refactor the way subdomain accounts are savedSimo Sorce1-1/+1
The original sysdb code had a strong assumption that only users from one domain are saved in the databse, with the subdomain feature, we have changed reality, but have not adjusted all the code arund the sysdb calls to not rely on the original assumption. One of the side effects of this incongrunece is that currently group memberships do not return fully qualified names for subdomain users as they should. In oreder to fix this and other potential issues surrounding the violation of the original assumption, we need to fully qualify subdomain user names. By savin them fully qualified we do not risk aliasing local users and have group memberhips or other name based matching code mistake a domain user with subdomain usr or vice versa.
2012-11-19SERVER: Check the return value of waitpidJakub Hrozek1-11/+27
We should at least print an error message and error out if waitpid() fails. https://fedorahosted.org/sssd/ticket/1651
2012-11-14Always start PAC responder if IPA ID provider is configuredSumit Bose1-0/+6
Since the PAC responder is used during the authentication of users from trusted realms it is started automatically if the IPA ID provider is configured for a domain to simplify the configuration. Fixes https://fedorahosted.org/sssd/ticket/1613
2012-11-14Add string_in_list() and add_string_to_list() with testsSumit Bose2-0/+69
string_in_list() and add_string_to_list() are two utilities for NULL terminated strings arrays. add_string_to_list() adds a new string to an existing list or creates a new one with the strings as only item if there is not list. string_in_list() checks if a given string is in the list. It can be used case sensitive or in-sensitive.

2012-11-08util_lock.c: sss_br_lock_file accepted invalid parameter valueMichal Zidek2-3/+7
Return EINVAL if number of tries is <= 0. Also the parameter retries was renamed to num_tries, so it is more obvious that it also includes the first try.
2012-11-06util: Added new file util_lock.cMichal Zidek2-0/+87
2012-11-06exit original process after sssd is initializedPavel Březina2-2/+30
https://fedorahosted.org/sssd/ticket/1357 Neither systemd or our init script use pid file as a notification that sssd is finished initializing. They will continue starting up next service right after the original (not daemonized) sssd process is terminated. If any of the responders fail to start, we will never terminate the original process via signal and "service sssd start" will hang. Thus we take this as an error and terminate the daemon with a non-zero value. This will also terminate the original process and init script or systemd will print failure.

2012-11-06add SSSDBG_IMPORTANT_INFO macroPavel Březina1-0/+1
We currently have only SSSDBG_FATAL_FAILURE macro that corresponds to original debug level 0. But there are several level 0 messages that are not actually failures but an important information. We should use this new macro to represent them.

https://fedorahosted.org/sssd/ticket/1495
2012-10-26Make sub-domains case-insensitiveSumit Bose1-1/+1
Currently the only type of supported sub-domains are AD domains which are not case-sensitive. To make it easier for Windows user we make sub-domains case-insensitive as well which allows to write the username in any case at the login prompt. If support for other types of sub-domains is added it might be necessary to set the case-sensitive flag based on the domain type.
2012-10-26sss_parse_name_for_domains: always return the canonical domain nameSumit Bose1-2/+7
Domains may have a flat or short name to save some keystrokes when typing fully qualified user names. Internally sssd will always use the canonical name to allow consistent processing.
2012-10-26Add replacement for krb5_find_authdata()Sumit Bose2-0/+19
krb5_find_authdata() is only available in MIT Kerberos 1.10 or higher. To allow sssd to be compiled on platform with lower version of MIT Kerberos a replacement call is added. Please note that on those platform the replacement call will only return an error. If the krb5_find_authdata functionality is really needed on those platform it must be implemented by a different patch.

2012-10-12Collect krb5 trace on high debug levelsJakub Hrozek2-0/+19
If the debug level contains SSSDBG_TRACE_ALL, then the logs would also include tracing information from libkrb5. https://fedorahosted.org/sssd/ticket/1539
2012-10-02remove left over principal selectionPavel Březina2-106/+0
https://fedorahosted.org/sssd/ticket/1303 Domain start up was taking too long when there are many principals in a kerberos keytab. We were looking up in the keytab two times. The first time we try to select a proper principal and remember it. The second call happens almost right after the first one and it is just a check if the principal exists in the keytab, without any output information other than success/failure. It is probably a left over from https://fedorahosted.org/sssd/ticket/781. This patch removes the second call.

2012-08-16Fix compilation error in Python murmurhash bindingsJakub Hrozek1-0/+2
The compilation produced an error due to missing declaration of uint32_t and a couple of warnings caused by different prototypes of argument parsing functions in older Python releases.
2012-07-23Extend category support in SELinux user mapsJan Zeleny1-6/+24
This patch adds the possibility for user/host category attributes to have more than one value. It also fixes semantically wrong evaluation of SELinux map priority.
2012-07-23Added some DEBUG statements into SELinux related codeJan Zeleny1-4/+24
2012-07-18Modify priority evaluation in SELinux user mapsJan Zeleny2-6/+45
The functionality now is following: When rule is being matched, its priority is determined as a combination of user and host specificity (host taking preference). After the rule is matched in provider, only its host priority is stored in sysdb for later usage. When rules are matched in the responder, their user priority is determined. After that their host priority is retrieved directly from sysdb and sum of both priorities is user to determine whether to use that rule or not. If more rules have the same priority, the order given in IPA config is used. https://fedorahosted.org/sssd/ticket/1360 https://fedorahosted.org/sssd/ticket/1395

* This broke corner cases when used with default_tkt_types = des-cbc-crc and DES enabled on an AD domain. * This is fixed in kerberos instead, in a more correct way and in a way which we cannot replicate.

2012-06-21Fix re_expression matching with subdomainsJan Zeleny1-15/+19
This patch fixes an issue which resulted in a need to initialize responder with data from local domain, otherwise it would not correctly detect requests for subdomains. Similar situation can occur if new subdomain is added at runtime. The solution is to ask for a list of subdomains in case there is a candidate domain identified in the process of matching re_expressions with given name.
2012-06-21UTILS: Fix segfault due to sss_parse_name_for_domainsStephen Gallagher1-7/+10
The recent fixes for per-domain parsing can cause a segfault in the netgroup processing if the domain isn't set to NULL when it's parsed as "any domain". https://fedorahosted.org/sssd/ticket/1383
