openssh unix dev - Sep 2005 - GSSAPI credentials deletion

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
