Description of Problem: Latest Rawhide Samba SRPMS (I looked at version 2.0.8-0.7.1) include a patch to set pam credentials. However, it suffers a fatal flaw. It presumes that there is one user per smbd, unfortunetly this is not how samba operates. One smbd can server multiple real and guest users, particuarly as used by Win2k Terminal Server. I have marked this as 'security' becouse this could (if I understand the patch infered its behaviour correctly) allow one user (including guest) to use the authentication tokons of another user served by the same smbd. This is mitigated however by the fact that plaintext authentication would be required for this to occur. In any case, the first user to exit would end the pam session, rendering the code useless. The correct way to do this is to attach the pamh to a user's vuid, and to pass that to the relevent functions as required. This however is a more significat change, but one I intend to look at at some time. (As a matter of note, Samba 2.2 now no longer uses any global variables in respect to PAM - but when it did their vaule was not kept between authentication calls in any case). At least this is my understanding, I would be happy to be proved wrong.
The current rawhide should have samba 2.2.0, making the issue obsolete.
I'm going to look at the original issue over the next few weeks, attaching the pamh to the vuid. If anybody wants to contact me regarding the orginal issue this code attempted to address (so I can reimplement it properly) I would appriciate it. E-mail: abartlet
