* UTIL: Add a function to convert id_t from a number or a nameJakub Hrozek2014-10-221-0/+2
| | | | | | | | | | | | We need a custom function that would convert a numeric or string input into uid_t. The function will be used to drop privileges in servers and also in the PAC and IFP responders. Includes a unit test to test all code that changed as well as a fix for a misnamed attribute in the csv_to_uid_list function synopsis.

* SSSD: Chown the log filesJakub Hrozek2014-10-201-0/+1
| | | | | | | | | We need to chown the log files before dropping root to make sure they are usable by the SSSD user. Unfortunately, we can't just rely on passing the fd opened by root, because we need to be also able to rotate the log files. Reviewed-by: Pavel Reichl <preichl@redhat.com>

| | | | | | | | | We used to only generate the [capaths] section on the IPA server itself, when running in a trusted setup. But we also found out that the capaths are often required to make SSO fully work, so it's better to always generate them. Reviewed-by: Alexander Bokovoy <abokovoy@redhat.com>

* Replace space: add some checksSumit Bose2014-09-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This patch adds some additional checks if the option for replacing spaces in user and group names is used. When replacing space with the replacement character it is checked if the name already contains the replacement character. If it does the unmodified name is returned because in this case a revers operation would not be possible. For the reverse operation is it checked if the input contains both a space and the replacement character. If this is true the unmodified name is returned as well, because we have to assume that it is the original name because otherwise it wouldn't contain both characters. Additionally a shortcut if the replacement characters is a space and tests for the new checks are added. The man page is updated accordingly.

* LDAP: tokengroups do not work with id_provider=ldapPavel Reichl2014-07-211-0/+5
| | | | | | | | | | | | | | | | | | With plain LDAP provider we already have a sdap_handle, so it should be possible that in the case where sdom->pvt == NULL sdap_id_op_connect_send() can be skipped and sdap_get_ad_tokengroups_send() can be already send with the sdap_handle passed to sdap_ad_tokengroups_initgr_mapping_send(). So we should only fail if sdom->pvt == NULL and sh == NULL. if find_subdomain_by_sid() failed we can check if there is only one domain in the domain list (state->domain) and in this case continue with this domain since the LDAP provider does not know about sub-domains and hence can only have one configured domain.

* NSS: Don't use printf(3) on user provided strings.Stef Walter2014-01-121-9/+3
| | | | | | | | | | | | | | | | | | | | This also fixes several corner cases and crashers. It's not prudent to pass user input to (even admin) input as a format string to printf, and various distros now check for this. This can cause accessing memory incorrectly, and various also various libc abort()'s. In addition various assumptions were made about full_name_format that aren't necessarily the case if the user uses a more complex format. Use safe-printf.c implementation for formatting full_name_format. Adapt the NSS resolver so it doesn't barf on formatted strings that are shorter than expected given a full_name_format. Tests added and updated appropriately.

| | | | | | | | | | | | The patch makes sure that a completely lower-cased version of a fully qualified name is used for case insensitive searches. Currently there are code paths where the domain name was used as configured and was not lower-cased. To make sure this patch does not break with old entries in the cache or case sensitive domains a third template was added to the related filters templates which is either filled with a completely lower-cased version or with the old version. The other two template values are unchanged.
