In 3.7.1p2, the sshd_config manpage talks about GSSAPICleanupCredentials, while servconf.c uses GSSAPICleanupCreds.

It looks to me like GSSAPICleanupCredentials doesn't work if UsePrivilegeSeparation is set to "no". Is this a bug, or am I doing something wrong? On a related note, is there a SERVER way to disable GSSAPIDelegateCredentials?

Hi, I am doing some kerberos testing with samba4 using ssh. I have setup samba4 using the howto at http://wiki.samba.org/index.php/Samba4/HOWTO and active directory seems to be working both with Windows and Linux clients. ssh unfortunately is not kerberos authenticating via GSSAPI. The client krb5.conf contains this: ===================================================== [libdefaults]

Hi friends, I have a one way outgoing trust between SAMBA trusting domain and AD trusted domain. SSH Authentication of a user belonging to the SAMBA domain works properly on a Linux computer which is a member of SAMBA domain. I would like to authenticate a trusted user from the AD domain on the same Linux computer with SSH. Currently it doesn't work. I am able to authenticate trusted accounts

Ah, and it that server allowed to "forward/exchange" that ticket? Try this on both servers and test again. GSSAPIAuthentication yes GSSAPICleanupCredentials no GSSAPIStrictAcceptorCheck no GSSAPIKeyExchange yes Which you need exaclty, i dont now, but i think you need to look in this area.. Think in this : Kerberos: Requested flags: renewable-ok, canonicalize, renewable, forwardable Which are allowed for the server(s)? Greetz, Louis > ----...

Hello, I have a problem dealing with GSSAPI credentials cleanup with OpenSSH 4.x (GSSAPI libs from Kerberos MIT's implementation 1.4.2). Although I use "GSSAPICleanupCredentials yes", credentials remain undeleted after connection. The same test with OpenSSH 3.9p1 is successful. Has anyone encountered the same problem? Best regards, Emmanuel
