I checked the krb5.conf on server and client and they seem exactly
alike to me :(

the server (kdc) krb5.conf:
 default = FILE:/var/log/krb5libs.log
 kdc = FILE:/var/log/krb5kdc.log
 admin_server = FILE:/var/log/kadmind.log

[libdefaults]
 ticket_lifetime = 24000
 default_realm = EXAMPLE.DK
 dns_lookup_realm = false
 dns_lookup_kdc = false

[realms]
 EXAMPLE.DK = {
  kdc = auth01.telmore.dk:88
  admin_server = auth01.example.dk:749
  default_domain = example.dk
 }

[domain_realm]
 .example.dk = EXAMPLE.DK
 example.dk = EXAMPLE.DK

[kdc]

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

and on the client:
[libdefaults]
 default_tkt_enctypes = des-cbc-crc;  des-cbc-md5
 default_tgs_enctypes = des-cbc-crc; des-cbc-md5
 ticket_lifetime = 24000
 default_realm = EXAMPLE.DK
 dns_lookup_realm = false
 dns_lookup_kdc = false

[realms]
 EXAMPLE.DK = {
  kdc = udp/auth01.example.dk:88
 }

[domain_realm]
 .example.dk = EXAMPLE.DK
 example.dk = EXAMPLE.DK

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

any obvious errors?
