Re: SASL GSSAPI authentication with Sun Java Directory Server 5.2P4

It's been awhile since I posted this, but for the record (and if anyone
encounters this in the future), this was a problem with the ldap/fqdn
principal keytab on the DS server. It needed to have a weaker enctype
(des-cbc-crc worked, though others probably do, as well), or else
apparently Solaris couldn't handle it.
Thanks for the followup. It's a bit puzzling still; where is the KDC hosted?
The principal's record in the KDC should contain keys encoded with all of its
supported enctypes. Changing the keytab on the server wouldn't change what
type of service tickets the KDC issues, that would still be controlled by
what the KDC knows and what the client supports.
At any rate, it's good to know that this is a problem area. Yet another
reason not to use SunDS...

I am trying to use OpenLDAP's ldapsearch to connect to a Sun DS 5.2
server using SASL/GSSAPI to authenticate. The setup works perfectly
fine on Solaris clients, but not on Linux ones using OpenLDAP's
ldapsearch (Debian sid on x86). Instead, it always gives the following
SASL/GSSAPI authentication started
ldap_sasl_interactive_bind_s: Invalid credentials (49)
additional info: SASL(-13): authentication failure: GSSAPI
Error: Unspecified GSS failure. Minor code may provide more
information (Unknown code 188)
This error is coming from the DS server (right?), so I know this may
not be OpenLDAP's problem. I was just wondering if anyone else had
encountered this problem, or if there are any workarounds or anything,
or if this is known to just not work at all.
I'm using the Cyrus SASL implementation with MIT Kerberos. I tried
this with ldapsearch 2.3.30 and 2.2.23.
