Description Andrew Merkert 2005-01-10 15:56:39 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Tyco 
Electronics 01/2003; SV1; .NET CLR 1.1.4322)

Description of problem:
As a large corporation using Linux to support both Windows PCs and 
various UNIX platforms, we would like to have the maximum number of 
groups that a user can be a member of increased from the current 
maximum of 32 to 64, 128, or 256 to allow for a more granular 
security configuration.

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

How reproducible:

Steps to Reproduce:
1. Add a user to 33 groups in the /etc/group file.
2. Change the permissions on a file so that only the 32nd group has 
access to the file.
3. Try to access the file (successful)
4. Change the permissions on the same file so that only the 33rd 
group has access to the file.
5. Try to access the file (unsuccessful)

Actual Results:  The first attempt is successful and the second 
attempt fails.

Internal RFE bug #144721 entered; will be considered for future releases.

Comment 4 Jeff Needle 2005-01-13 13:11:43 UTC
This was already discussed in internal bug #133299.  We cannot change NGROUPS
for RHEL3 due to Kernel ABI issues, but for our upcoming RHEL4 release, this
restriction will be lifted.
