Package: kdm
Version: 4:3.3.2-1sarge1
Severity: important


Hi,

on our network we have users, who have their home directory on an
OpenAFS server. In order to get access to the home directory, the
libpam-openafs-session pam-module is used to obtain the needed afs token
upon login.

If I upgrade the kernel to version 2.6.16 (vanilla) (or newer), a login
with kdm is not possible anymore. There is no possiblity to write to the
users home directory because of missing afs tokens in the environment.
Till kernel version 2.6.15 (vanilla) this worked. The pam configuration
did not change.

I started debugging libpam-openafs-session, but as far as I can
overlook the situation, a token is successfully retrieved for the user.
However it seems to get lost somewhere in the environment of kdm.

gdm does not have this bug (using the same pam configuration like kdm).
Also console logins are working correctly.

Our pam configuration:

kdm:
auth    requisite       pam_nologin.so
auth    required        pam_env.so
@include common-auth
@include common-account
session required        pam_limits.so
@include common-session
@include common-password

common-auth:
auth    optional        pam_group.so
auth    sufficient      pam_krb5.so ignore_root use_first_pass forwardable
auth    required        pam_unix.so try_first_pass nullok secure

common-account:
account optional        pam_krb5.so ignore_root
account required        pam_unix.so

common-session:
session optional        pam_krb5.so ignore_root
session required        pam_unix.so
session optional        pam_openafs_session.so ignore_root

common-password:
password   sufficient pam_krb5.so ignore_root
password   required   pam_unix.so nullok md5


A current Debian Testing system is not affected by this bug.
