Are you trying to use LDAP accounts by any chance?  I've yet to get that to work for me as webmin user accounts.

Subject: [webmin-l] Issues setting up PAM authentication

I am setting up a new Webmin/usermin instance and am running into an issue with getting PAM authentication working.


I have installed the Authen::PAM perl module, and have configured Webmin to use PAM authenticatyion when possible, but when I try to log in with anything other than the initial admin user, I get a 401 response code.


I don’t see anything other than the 401 in any logs & am not sure how to troubleshoot this one. Any ideas?
