[PATCH] Mutual authentication, keytabs, and SMB session keys
Luke Howard
lukeh at PADL.COM
Mon Feb 24 06:11:52 GMT 2003
Here's a revised patch that cleans up a few of the issues you mentioned.
You may want to omit the USE_KEYTAB patch to passdb/secrets.c: we don't
actually use that, and without support for updating the secret, it may
be of limited use.
