Description Andreas Schneider 2013-09-10 07:52:35 UTC
Description of problem:

With the change of the default location of the KRB5 credential cache we have added KEYRING as a value for the option 'krb5_ccache_type' in the pam_winbind.conf file.

    krb5_ccache_type = KEYRING

As authconfig is setting or changing this variable we need to update it to reflect the change in the system default.

Comment 2 Tomas Mraz 2013-09-11 10:54:45 UTC
Nope, authconfig does not change or set the krb5_ccache_type value in any way.
Also it does not touch pam_winbind.conf at all.

It writes winbind configuration to smb.conf.

Comment 3 Andreas Schneider 2013-09-11 11:40:13 UTC
Really? Oh, cause for

authconfig --enablewinbindoffline

you need to set

  cached_login = yes

in /etc/security/pam_winbind.conf.

This needs probably to be fixed and we should add an option:

authconfig --enablewinbindkrb5

which sets in smb.conf:

  kerberos method = secrets and keytab

and in pam_winbind.conf:

  krb5_auth = yes
  krb5_ccache_type = KEYRING

Comment 4 Andreas Schneider 2013-09-13 07:31:07 UTC
Should I create another bug for the cached login stuff or is one fine? Let me know if I could help or should review code.

Comment 5 Tomas Mraz 2013-09-13 09:57:01 UTC
I think another bug for cached login would be good because the current way does not work.

And the --enablewinbindkrb5 is rather a feature.

Comment 6 Tomas Mraz 2013-10-30 14:53:05 UTC
To avoid messing with another file could these options (krb5_auth and krb5_ccache_type) be set in the /etc/pam.d/system_auth as pam_winbind.so parameters?

Comment 7 Andreas Schneider 2013-10-31 10:52:43 UTC
Yes, you can also pass then to the pam module.

pam_winbind.so krb5_auth=yes krb5_ccache_type=KEYRING

Comment 8 Tomas Mraz 2013-10-31 16:52:26 UTC
I'd like to solve this by rebasing authconfig as I am doing the development upstream and there will be no changes unrelated to RHEL-7 development.
