hi, currently we had a heavy problem with our SSO configuration. u can see in subject which configuration we have. its a apache2 with kerberos modules and the users are in an MS active directory.
everything works rather fine. but some of the users get a login message dialog box few times a day. after the login with their username and password everything works fine. some of them getting the box again after a while and some don't. for the most of all users it works fine. but its not only a special group who had this login box problem. the most of all users had alleady this problem not when a User get the Login Box we found this messages in the Apache logs : [Wed Nov 21 12:11:03 2007] [debug] src/mod_auth_kerb.c(1483): [client 192.168.2.115] kerb_authenticate_user entered with user (NULL) and auth_type Kerberos [Wed Nov 21 12:11:03 2007] [debug] src/ mod_auth_kerb.c(1483): [client 192.168.2.115] kerb_authenticate_user entered with user (NULL) and auth_type Kerberos [Wed Nov 21 12:11:03 2007] [debug] src/mod_auth_kerb.c(1174): [client 192.168.2.115] Acquiring creds for HTTP/[EMAIL PROTECTED] [Wed Nov 21 12:11:03 2007] [debug] src/mod_auth_kerb.c(1314): [client 192.168.2.115] Verifying client data using KRB5 GSS-API [Wed Nov 21 12:11:03 2007] [debug] src/mod_auth_kerb.c(1330): [client 192.168.2.115] Verification returned code 589824 [Wed Nov 21 12:11:03 2007] [debug] src/mod_auth_kerb.c(1357): [client 192.168.2.115] Warning: received token seems to be NTLM, which isn't supported by the Kerberos module.

We check allready different Browsers and we have this Problem with IE 6 & 7 and Firefox. I hope someone here had a great Idea what we can do. greetz palm ________________________________________________ Kerberos mailing list Kerberos@mit.edu https://mailman.mit.edu/mailman/listinfo/kerberos
