If this option is set, pam_winbind will only succeed if the user is a member of the given SID or NAME. A SID
can be either a group-SID, an alias-SID or even an user-SID. It is also possible to give a NAME instead of the
SID. That name must have the form: <parameter>MYDOMAIN\mygroup</parameter> or
- <parameter>MYDOMAIN\myuser</parameter>. pam_winbind will, in that case, lookup the SID internally. Note that
- NAME may not contain any spaces. It is thus recommended to only use SIDs. You can verify the list of SIDs a
- user is a member of with <command>wbinfo --user-sids=SID</command>.
+ <parameter>MYDOMAIN\myuser</parameter> (where '\' character corresponds to the value of
+ <parameter>winbind separator</parameter> parameter). It is also possible to use a UPN in the form
+ <parameter>user@REALM</parameter> or <parameter>group@REALM</parameter>. pam_winbind will, in that case, lookup
+ the SID internally. Note that NAME may not contain any spaces. It is thus recommended to only use SIDs. You can
+ verify the list of SIDs a user is a member of with <command>wbinfo --user-sids=SID</command>.
