HI all, I am having problems getting challenge/response auth working with samba 2.2.8a. Samba was configured with the --with-winbind and --with-winbind-auth-challenge options. added the following to smb.conf workgroup = <domain> security = domain password server = <domaincontroller> winbind uid = 10000-20000 winbind gid = 10000-20000 winbind use default domain = yes encrypt password = yes after joining the domain and running wbinfo -t (returned secret is good), I attempted a wbinfo -a domain\\user%password and only recieved "Plaintext password authentication succeeded". I don't recieve any messages regarding "challenge/response". Why don't I recieve a challenge/response message? I definately compiled using the appropriate options, and I have used the steps above on other systems and it worked fine. Thanks for any help. -Haydn
