Description Lukas Hejtmanek 2016-12-14 19:03:38 UTC 
Description of problem:
openssh as of version 6.6.1p1-31 clears supplementary groups for logged user if chroot is enabled (e.g. for sftp only access).

Version-Release number of selected component (if applicable):
6.6.1p1-31

How reproducible:
enable Chrootdirectory option, check user groups when user logs in.


Steps to Reproduce:
1. enable chrootdirectory (chrootdirectory / is sufficient)
2. make user log in
3. check user groups (id -G)

Actual results:
only primary group is assigned


Expected results:
primary group with supplementary groups should be assigned

Additional info:
I guess (but really just guess) this is the offending patch: openssh-6.6p1-chroot-capabilities.patch
