Description Adam 2005-01-29 21:02:02 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5)
Gecko/20041111 Firefox/1.0

Description of problem:
When logging into the machine via ssh my secondary groups are not set
as reported by the id command.

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

How reproducible:

Steps to Reproduce:
1. Log in via ssh
2. Type 'id'
3. Only primary group is set, none of secondaries

Actual Results:  Only the primary group is set. If I type 'id' then I
see only my primary group. If I type 'id <me>' then I see all the
groups I should be in.

Expected Results:  My 3 secondary groups should also be set

Additional info:

This machine was upgraded to FC3 from FC2 via 'yum upgrade'. I have a
number of other systems where secondary groups are set as expected.
I've  tried different versions of pam, with no effect. I do not have
console access as the machine is in another country, so I can't try
logging in from it to see if it works ok.
Comment 1 Adam 2005-01-29 21:59:39 EST
This may not be ssh specific, as su also fails to set the secondary
Comment 2 Tomas Mraz 2005-01-31 03:10:03 EST
I'm sorry but I cannot reproduce this bug. (Neither for ssh nor for
su.) Do you have privilege separation on in the sshd config?
What glibc version do you have?
Comment 3 Adam 2005-02-01 03:01:27 EST
I think I have now resolved the issue via strace's of the su process.
When nscd is running, only the primary group is assigned, and when I
stop nscd, all works as expected. Next I'll try to figure why nscd is
acting up.
Feel free to either close this bug or reassign it to nscd.

I have narrowed this down. If I disable group caching (enable-cache
no), then secondary groups are not assigned. This is the whole group
section from my nscd.conf file.

        enable-cache            group           no
        positive-time-to-live   group           3600
        negative-time-to-live   group           60
        suggested-size          group           211
        check-files             group           yes
        persistent              group           yes
        shared                  group           yes

If I change enable-cache to yes, then secondary groups are assigned
