Dear sir/mdm
we encountered this issue after update to 6u121. The issue does not happen for 6u31
2019-07-19 16:00:29,405 DEBUG [http-8080-2] (DirectoryUtils.java:231) - javax.naming.AuthenticationException: GSSAPI [Root exception is javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Server not found in Kerberos database (7))]]
Any help is much appreciated.
Many thanks!
