pam_winbind — PAM module for Winbind
This tool is part of the samba(7) suite.
pam_winbind is a PAM module that can authenticate users against the local domain by talking to the Winbind daemon.
pam_winbind supports several options:
Gives debugging output to syslog.
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, a alias-SID or even a user-SID. It is also possible to give a NAME instead of the SID. That name must have the form: MYDOMAIN\mygroup or MYDOMAIN\myuser. 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 wbinfo --user-sids=SID.
By default, pam_winbind tries to get the authentication token from a previous module. If no token is available it asks the user for the old password. With this option, pam_winbind aborts with an error if no authentication token from a previous module is available.
Set the new password to the one provided by the previously stacked password module. If this option is not set pam_winbind will ask the user for the new password.
