Authentication client via Kerberos (Heimdal) and LDAP backend
Dennis GuseTo use the provided authenfication mechanism from g00se.org on g00se.org :D. I installed libpam-heimdal and configured nss.
Kerberos configuration: /etc/krb5.conf
1 [libdefaults]
2 default_realm = G00SE.ORG
3 default_keytab_name = /etc/krb5.keytab
4 ticket_lifetime = 28800
5 default_etypes = des3-hmac-sha1 des-cbc-crc des-cbc-md5
6 default_etypes_des = des3-hmac-sha1
7 des-cbc-crc des-cbc-md5

12 [domain_realm]
13 g00se.org = G00SE.ORG
14 .g00se.org = G00SE.ORGThe pam configuration to use the heimdal KDC: /etc/pam.d/kerberos

1 passwd: compat *ldap*
2 group: compat *ldap*That's all! As root you can now check if everything runs: getent passwd and you will see all your local accounts and the provided central ones! I hope everything is cool!!!
