GSSAPI / SASL problems of sasl2-bin on Ubuntu 10.04.4

[John Mok]

Hi,

I have succeeded using GSSAPI SASL for OpenLDAP + Postfix access on 
Ubuntu 8.04.4. When I made the same setup on Ubuntu 10.04.4 :-

 >ldapwhoami -Y GSSAPI

it returned an error (80).

When I tried libsasl2-modules-gssapi-mit, it returned (key table entry 
not found). When I tried libsasl2-modules-gssapi-heimdal, it returned 
"No credentials were supplied, or the credentials were unavailable or 
inaccessible ...". I checked with ktutil list and it listed the kerberos 
principals from Windows 2003 correctly.

I checked if GSSAPI of saslauthd working or not :-

 >sasl-sample-server -m GSSAPI -s ldap

 >sasl-sample-client -m GSSAPI -s ldap -n imapsv04.sml.citizen.co.jp

It failed with "unable to decode ....". I tried the testings on Ubuntu 
8.04.4 and they passed.

Is there any problem with sasl2-bin package on Ubuntu 10.04.4? I help 
someone could point how to solve the GSSAPI / SASL problems on Ubuntu 
10.04.4.

Thanks a lot.
