Create a new group without a password, or use an existing group that doesn't have a password. I happened to discover this using the "mock" group. 2. Add a already logged-in user to a group in /etc/group. 3. Note that the current user login session is not a member of that group, i.e., by using the "id" command at a shell prompt 4. Issue a "newgrp <groupname>" command. 5. When prompted, enter the user's password. Actual results: crypt: Invalid argument Expected results: user gets a subshell with the group in the group list (as shown by the "id" command) Additional info: This is due to a change in behavior in crypt() in glibc 2.17. It has been reported upstream along with a patch that fixes it: https://alioth.debian.org/tracker/index.php?func=detail&aid=314234 I have locally rebuilt the RPM with that patch added, and it solves the crypt problem. The patch applied cleanly with -p1. Note that with the crypt problem solved, newgrp then gives different errors: setgroups: Operation not permitted setgid: Operation not permitted However, that is a completely independent bug or configuration error that I am still investigating.

If the user is member of the group, he will never be prompted for a password when newgrp groupname is issued. And when he is not and there is no password in group/gshadow set this bug will just affect the message issued. Though applying the patch is correct thing as crypt: Invalid argument is not a particularly good message.

Doesn't the user get prompted for their own password in that case? I think I last experienced this use case with F14, and I don't remember whether I was prompted for a password or not. I might fire up F14 in a VM to check.
