Bug Description

[Impact]
password changes don't currently work unless pam_cracklib is installed, or the use_authtok is dropped from the libpam-sss pam-auth-update file.

[Test case]
install sssd & libpam-sss on an LDAP client, then try to change the password of a networked user.

[Regression potential]
This bug has basically forced users to modify the (package owned) file on their own, but the new version should still work in all cases.

--

The priority of the libpam-sss pam-auth-update config file needs to be lower than for pam_unix, so that local users always work, despite the state of the sssd daemon. This causes a problem with the password stack, where pam_sss needs to be above pam_unix, so that if pam_cracklib is installed password changes still work. Otherwise it would be broken in one of the cases, depending on if use_authtok is set or not.

The fix for this is to split the password stack from pam_sss config separate from the rest, and use a higher priority there.

This is fixed in raring, needs an SRU to precise and quantal.
