Hello. I am using krb5/winbind authentication, and having the same problem. I have tried the patch linked by levien, and it works well with local users, but completely breaks sudo for domain users (before applying the patch, i was able to use sudo with domain users, the problem was only with gksu).
Actually, I think it is a bug, because I have noticed the following: In a default Ubuntu installation, sudo presents the prompt "Password:", with an uppercase "P". But after configuring pam-krb5, it presents the prompt "password:", with a lowercase "p". I am sure this bug is extremely easy to fix for any who knows where in the source is located the prompt string. So PLEASE, you smart guys, fix it for us begginers! ;) Thanks a lot. -- gksudo fails if using libpam-krb5 for password auth https://bugs.launchpad.net/bugs/15093 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
