Kerberos Authentication error

Hi ,

I am trying to authenticate my id on client server with Kerberos and receiving below error


kinit rpagadala@BDC.soft.net
kinit: Cannot contact any KDC for realm 'BDC.soft.net' while getting initial credentials

Please find krb5.conf on the client server configuration which is same as the Kerberos master server .

Code:
 
[logging]
 default = FILE:/var/log/krb5libs.log
 kdc = FILE:/var/log/krb5kdc.log
 admin_server = FILE:/var/log/kadmind.log
[libdefaults]
 default_realm = BDC.soft.net ( this is just an example ) 
 dns_lookup_realm = false
 dns_lookup_kdc = false
 ticket_lifetime = 24h
 renew_lifetime = 7d
 forwardable = yes
[realms]
 BDC.soft.net = {
  kdc = server1:88
  kdc = server2:88
  admin_server = server1:749
  default_domain = soft.net
 }
[domain_realm]
 .soft.net = BDC.soft.net 
 soft.net = BDC.soft.net 
[appdefaults]
 pam = {
   debug = false
   ticket_lifetime = 36000
   renew_lifetime = 36000
   forwardable = true
   krb4_convert = false

Code:
  kdc = server1:88
  kdc = server2:88

This looks like a resolution problem. Can "server1" and "server2" be resolved to valid IP addresses? Sometimes backwards resolution is also necessary, therefore check not only if "server1" resolves, but also if the IP address you get that way resolves to the name "server1" in turn (same for "server2").

I hope this helps.
