Mario-

Take a look at the stock /etc/krb5.conf, and change all the
example.com/EXAMPLE.COM settings to match your domain/realm
settings. Once you can kinit as zbr, you'll know that your kerberos
setup is functional.

For example, at UCSD, the campus active directory is (some would argue,
cleverly :) called AD.UCSD.EDU, so a working krb5.conf looks like

[logging]
 default = FILE:/var/log/krb5libs.log
 kdc = FILE:/var/log/krb5kdc.log
 admin_server = FILE:/var/log/kadmind.log

[libdefaults]
 default_realm = AD.UCSD.EDU
 dns_lookup_realm = false
 dns_lookup_kdc = false

[realms]
 AD.UCSD.EDU = {
  kdc = ad.ucsd.edu:88
  admin_server = ad.ucsd.edu:749
  default_domain = AD.UCSD.EDU
 }

[domain_realm]
 .ucsd.edu = AD.UCSD.EDU
 ucsd.edu = AD.UCSD.EDU
 .ad.ucsd.edu = AD.UCSD.EDU
 ad.ucsd.edu = AD.UCSD.EDU

[kdc]
 profile = /var/kerberos/krb5kdc/kdc.conf

[appdefaults]
 pam = {
   debug = false
   ticket_lifetime = 36000
   renew_lifetime = 36000
   forwardable = true
   krb4_convert = false
 }

This is pretty much the stock krb5.conf after replacing all the
example.com/EXAMPLE.COM with ad.ucsd.edu/AD.UCSD.EDU with a very minor
tweak [domain_realm] section.
