As I use ksu to the user it seems pam_afs_session can work well.

[root@submit ~]# kinit huli
Password for huli@HERDINGCAT.INTERNAL:
[root@submit ~]# ksu huli
Changing uid to huli (501)
[huli@submit root]$

But as I use su command it won't work can report that cannot access
the home dir.

[root@submit ~]# kinit huli
Password for huli@HERDINGCAT.INTERNAL:
[root@submit ~]# su -l huli
su: warning: cannot change directory to
/afs/herdingcat.internal/home/huli: Permission denied
-bash: /afs/herdingcat.internal/home/huli/.bash_profile: Permission denied

Here's the /etc/pam.d/system-auth and /etc/pam.d/su configuration files.

I noticed that su has quote system-auth but it seems not work properly.

Could anyone tell me what's going on?

Thanks very much.
