7050e05742 auth: Store group attributes in auth_user_info_dc
Group expansion, performed in dsdb_expand_nested_groups(), now
incorporates a check of the type of each group. Those that are resource
groups receive the SE_GROUP_RESOURCE bit in the attributes which are now
carried alongside each group SID.

Whereas before, in auth_convert_user_info_dc_sambaseinfo() and
auth_convert_user_info_dc_saminfo6(), we invariantly used the flag
combination SE_GROUP_MANDATORY | SE_GROUP_ENABLED_BY_DEFAULT |
SE_GROUP_ENABLED to set attributes in the PAC, we now take the correct
attributes from user_info_dc.
