Hi,
the attached patches implement ticket #2073 -- the possibility to extend the LDAP attribute map with custom attributes.
All attributes are saved to sysdb with the 'extra_' prefix so that the custom attributes can be distinguished from the sysdb schema.
The first patch fixes a mostly unrelated bug, which I found when writing unit tests.
[PATCH 1/3] LDAP: Fix one-by-one bug in sdap_copy_opts The sdap_copy_opts function copied all the arguments except for the sentinel.
[PATCH 2/3] LDAP: Make it possible to extend an attribute map https://fedorahosted.org/sssd/ticket/2073
This commit adds a new option ldap_user_extra_attrs that is unset by default. When set, the option contains a list of LDAP attributes the LDAP provider would download and store in addition to the usual set.
The attributes are fetched in sysdb with the 'extra_' prefix to not conflict with the sssd sdap maps.
[PATCH 3/3] Make LDAP extra attributes available to IPA and AD https://fedorahosted.org/sssd/ticket/2073
