Hi Team, I have recently migrated Kerberos principals using the below command from one KDC to another KDC, post-migration kinit is not working and it is throwing some error whereas the same identity is working in the original KDC. Can you please help us in identifying the error? Did I make any mistakes while migrating the principles? Command Used - kdb5_util dump -verbose dumpfile and logged in to other KDC and executed the restore kdb5_util restore -verbose /tmp/dumpfile Error: KRB5_TRACE=/dev/stdout kinit testuser [8962] 1645765308.654184: Getting initial credentials for testuser@EXAMPLE.COM [8962] 1645765308.654186: Sending unauthenticated request [8962] 1645765308.654187: Sending request (181 bytes) to EXAMPLE.COM [8962] 1645765308.654188: Resolving hostname stg-hdplucykrb101.phonepe.nb6 [8962] 1645765308.654189: Sending initial UDP request to dgram 10.57.55.228:88 [8962] 1645765308.654190: Received answer (163 bytes) from dgram 10.57.55.228:88 [8962] 1645765308.654188: Resolving hostname kdc.example.com [8962] 1645765308.654191: Sending DNS URI query for _kerberos.EXAMPLE.COM.
