Re: User login issue

HI Roman,

Hi folks,

Yesterday, I came across the following entry in /var/log/auth.log:
Feb 6 11:03:38 tjener su: pam_krb5(su:auth): (user roman) credential verification failed: Cannot find key for host/tjener.intern@INTERN kvno 16 in keytab 

I also had a closer look at the following script:
/usr/share/debian-edu-config/tools/copy-host-keytab

This then lead me to the solution of my authentication problem.
My file /etc/krb5.keytab was missing many entries preventing successful user logins. Executing the script fixed this finally. 

Kind regards,
Roman


If you run an old version of TJENER, you might be facing this bug:

Please adjust your gosa-modify-host script in /usr/share/debian-edu-config/tools/ as shown here:
