I successfully installed and configured krb5 on a Red Hat 6.4 server, now I can authenticate against an active directory with kerberos.

pam_mount is installed and configured, but it only mounts a cifs share, if I first enter the command

kinit username

on the host before logging in. Then I make a kdestroy and try it again, but it doesn't mount the share anymore.

So my conclusion is, that there is no kerberos ticket for pam_mount. But why, if I can login with my kerberos account?

this is my pam_mount.conf.xml:

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE pam_mount SYSTEM "pam_mount.conf.xml.dtd">

<volume fstype="cifs" ssh="0" server="" 
path="A_21_Home11$/%(USER)" mountpoint="~" options="sec=krb5" user="*" />

<logout wait="0" hup="0" term="0" kill="0" />

<mkmountpoint enable="1" remove="true" />


This is my /etc/pam.d/system-auth:

auth        required
auth        sufficient nullok try_first_pass
auth        requisite uid >= 500 quiet
auth        sufficient use_first_pass
auth        required
auth        required

account     required broken_shadow
account     sufficient uid < 500 quiet
account     [default=bad success=ok user_unknown=ignore]
account     required

password    requisite retry=3 type=
password    sufficient shadow nullok try_first_pass use_authtok
password    sufficient use_authtok
password    required

session     optional revoke
session     required
session     [success=1 default=ignore] service in crond quiet use_uid
session     required
session     optional use_authtok
session     optional

What does klist -f show you at various points in this process? I'm guessing that you aren't getting forwardable tickets at some point. You can test this with kinit -f . Check the pam section of appdefaults in krb5.conf. Setting forwardable=true and external=sshd may help. – chuck May 16 '13 at 15:52
