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 " 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=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.

[Touch-packages] [Bug 1355111] Re: newgrp fails with crypt: Invalid argument
To make it more clearly, I have attached another logfile. This new one is from Ubuntu 12.04 in the same environment as above. If you diff it with the stracenewgrp.log you can see, that in Ubuntu 14.04 the newgrp tries to allocate files associated to the language settings in /usr/share/locale while this is not the behaviour in 12.04. For what are those files located in the locales needed? The files it tries to access are not installed nor can they be installed as far as I know (please correct me if I am wrong here). It seems to me that it uses these files for the whole group handling which does not make sense at all to me. The /etc/login.defs does make a lot more sense... Hope this helps.

[Touch-packages] [Bug 1355111] Re: newgrp fails with crypt: Invalid argument
I had a look in src/newgrp.c I wonder why the variable grp is overwritten several times, before check_perms is called. In my understanding, this means the last found group entry wins. If I have following group entries in my environment: #From /etc/passwd comgrp:x:27:user1 #From NIS/LDAP or something similar comgrp:x:27:user2 #From /etc/gshadow comgrp:*::user3 user1 and user2 aren't able to change primary group to comgrp because check_perms only sees user3 in that group. I had expected that all three users are able to change to the comgrp. What is the correct behaviour? And why?
