Hi,
I'm currently trying to set up authentication between a client that uses
the MIT GSSAPI implementation to obtain its kerberos credentials and to
initialize the security context and a Server/Service that uses
Microsofts SSPI methods to authenticate and accept a securtiy context.
I'm using a heimdal KDC for authentication and for providing the service
tickets.
I've already successfully verified that the following combinations work
(both client and service running on the same Windows XP machine):
Client Service
------------------
GSSAPI GSSAPI
SSPI GSSAPI
SSPI SSPI
But if I obtain the service ticket using the GSSAPI methods and try to
accept the respective securtiy context in the service using
AcceptSecurityContext(...) from MS's SSPI, I always get
SEC_E_LOGON_DENIED as return code. AS stated above. Using the same
authentication information (username, password and realm) with SSPI's
InitializeSecurityContext(...), the resulting ticket is verified by the
test-service.
I already tried to introduce a mapping of the kerberos user principal
([EMAIL PROTECTED]) to a local user account (test-user) but
this didn't help either. Is the group that test-user belongs to of any
relevance? I set up test-user to be a member of guests only...
Is this a Microsoft incompatibility issue or is there something special
that needs to be regarded if trying to use GSSAPI together with SSPI?
Best Regards,
Daniel.
