SASL/GSSAPI authentication error

[Frederick Kramer <kramer@ikf.uni-frankfurt.de>]

Hello,

I have authentication problems while accessing the LDAP database. Each 
attempt to view or modify the DB leads to this error:

[root@mysystem]~> ldapwhoami
SASL/GSSAPI authentication started
ldap_sasl_interactive_bind_s: Local error (-2)
	additional info: SASL(-1): generic failure: GSSAPI Error: Unspecified 
GSS failure.  Minor code may provide more information (No credentials cache 
found)

On the other hand users can log on, change their passwords and so on - all 
that's working fine.

I found some similar problems in the web but no answer to those helped me to 
solve this. I suppose it's not a big thing and apologize for my limited 
understanding of ldap and authentification procedures.


Thanks for any help
Best regards

Fred
