Client not found or locked out

When we use the am_kinit command to test an AIX®, Linux®, or Solaris server key table, you receive the following error:
Unable to obtain initial credentials. Status 0x96c73a06
Client not found in Network Authentication Service database
or client locked out. 
The key table does not have a key for the specified principal. Check Whether an error was made when the principal was typed, or Whether the key table was generated incorrectly. We can use the Kerberos am_ktutil commands to check which keys are in the key table. For details about this procedure, see Validating keys in key tables.
