Looking for some advice on how to proceed or if anyone has had the same
issue; google hasn't come to my rescue yet:


Our Active Directory 2003 domain is called: GGG.LOCAL
Our userprincipalnames are setup to match our smtp address, in this case
username@grey.com

I can kinit successfully with:  username@GGG.LOCAL
But not with:  username@grey.com _or_ username@ggg.local ; error message
is: "kinit(v5): KRB5 error code 68 while getting initial credentials"

Running Centos 5.2 with the following krb5 packages installed:

krb5-libs-1.6.1-31.el5_3.3
pam_krb5-2.2.14-1.el5_2.1
pam_krb5-2.2.14-1.el5_2.1
krb5-libs-1.6.1-31.el5_3.3
krb5-workstation-1.6.1-31.el5_3.3
krb5-devel-1.6.1-31.el5_3.3


Following SRV record was manually added:   _kerberos._tcp.grey.com 0 100
88 dc.ggg.local.
Following is /etc/krb5.conf:

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

[libdefaults]
 default_realm = GGG.LOCAL
 dns_lookup_realm = true
 dns_lookup_kdc = true
 ticket_lifetime = 24h
 forwardable = yes

[domain_realm]
 .ggg.grey.global = GGG.LOCAL
 ggg.grey.global = GGG.LOCAL
 .grey.com = GGG.LOCAL
 grey.com = GGG.LOCAL

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