pam_mount network share using AD creds

Hi - Rather than dup a question, I want to x-post a question I put on stackoverflow which isn't getting much traffic. In short, I'm having trouble configuring pam_mount to auto-mount a network drive individually for each user, using their AD credential, upon login. See logs and question here:

Please answer here or there. I'll close out the SO question if answered here. Thanks
