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): kernel-2.4.21-20.EL How reproducible: Always 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. Additional info:
Internal RFE bug #144721 entered; will be considered for future releases.
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.
