I'm having trouble getting kaddressbook (in kontact) to bind to OpenLDAP
via SASL/GSSAPI. I have a valid ticket, but when I try to connect I get
this error popup:

    Authorization failed, ldap://server.cise.ufl.edu:389 
    authentication not supported

This message is sent to syslog:

   kio_ldap [kdeinit] kio_ldap ldap 
   No worthy mechs found

I have the LDAP addressbook configured as follows:

	User		: user
	BindDN		: 
	Realm		: CISE.UFL.EDU
	Password	:
	Host		: server.cise.ufl.edu
	Port		: 389
	LDAP Version	: 3
	Size Limit	: default
	Time Limit	: default
	DN		: dc=cise,dc=ufl,dc=edu
	Filter		:
	Security	: No (no tls)
	Authentication	: SASL/GSSAPI

A connecton is made to the ldap server and then the error message pops up.

   conn=4608 fd=31 ACCEPT from IP= (IP=
   conn=4608 op=0 UNBIND

What is odd is that I'm currently using SASL/GSSPI for both IMAP and SMTP
authentication with no problems. I can also using SASL/GSSAPI to bind to 
the ldap server using ldapsearch:

   /usr/bin/ldapsearch -H ldaps://server.cise.ufl.edu -Y GSSAPI -b

   SASL/GSSAPI authentication started
   SASL username: jfh at CISE.UFL.EDU
   SASL SSF: 56
   SASL installing layers

   # jfh, Users, cise.ufl.edu
   dn: uid=jfh,ou=Users,dc=cise,dc=ufl,dc=edu

I also get a valid ldap ticket this way:

   % klist
   Credentials cache: FILE:/tmp/krb5cc_987
           Principal: jfh at CISE.UFL.EDU

     Issued           Expires          Principal

   May  1 08:37:54  May  1 13:36:34  imap/server.cise.ufl.edu at CISE.UFL.EDU
   May  1 09:36:38  May  1 13:36:34  ldap/server.cise.ufl.edu at CISE.UFL.EDU

Is this something I'm doing wrong, or perhaps is there something wrong
with the way kio_ldap is compiled on SuSE ?
