title: postgreSQl 12 with GSSAPI authenticate
body: <p>I have been setup an authentication with Postgresql 12 using gssAPI on centos.I follow an example :<a href="https://paquier.xyz/manuals/postgresql/kerberos/" rel="nofollow noreferrer">https://paquier.xyz/manuals/postgresql/kerberos/</a> .But when i finish and run to conect with gssapi:</p>
  
  <p>"psql -U "postgres/myrealm.example@MYREALM.EXAMPLE" -h myrealm.example postgres"
  and i met an error :</p>
  
  <p>psql: FATAL:  could not accept GSSAPI security context</p>
  
  <p>FATAL:  accepting GSS security context failed</p>
  
  <p>DETAIL:  Unspecified GSS failure.  Minor code may provide more information: Key table entry not found</p>
  
  <p>I want to know  if I'm missing any configuration steps/commands or implementing something wrong.Any kind help is highly appreciated. Thanks in advance. </p>
