Hi John,
Thnks for your answer. Here are the content of /etc/krb5.conf and klist
-ke. I agree that there can be siomething missing, that was working
before...
]# cat /etc/krb5.conf
[logging]
default = FILE:/var/log/krb5lib.log
[libdefaults]
ticket_lifetime = 24000
default_realm = LAB-LPP.LOCAL
default_tk_enctypes = des3-hmac-sha1 des-cbc-crc
default_tgs_enctypes = des3-hmac-sha1 des-cbc-crc
dns_lookup_realm = true
dns_lookup_kdc = true
[realms]
LAB-LPP.LOCAL = {
kdc = pc-lpp1.lab-lpp.local:88
kdc = pc-lpp2.lab-lpp.local:88
kdc = pc-lpp3.lab-lpp.local:88
kdc = pc-lpp4.lab-lpp.local:88
kdc = pc-lppx.lab-lpp.local:88
admin_server = pc-lpp1.lab-lpp.local:749
default_domain = LAB-LPP.LOCAL
}

.lab-lpp.local = LAB-LPP.LOCAL
lab-lpp.local = LAB-LPP.LOCAL

It is a local domain because it spans multiple real DNS domains.
