    /etc/group and groups not working correctly on AIX 5.3 ML4. This is preventing groups/departments/projects from access information. Splitting into separate groups is not a solution.

    This is just a hunch, but are the groups maintained externally to AIX? Looks to me like there are some extraneous characters in your /etc/group file that are not visible. I've seen something similar if the /etc/group file is edited on windows and them ftp'd as binary rather than ascii. If you vi the group file, I'm suspecting you will see ^M characters or something similar.

    Nope, no special characters. That would be nice. ;-)

    I did an closed APAR at IBM, but no patch:

    Possible work around for a group with about 200 users:

    Only have a single group entry in /etc/group for each group, instead of multiple entries. Each single group entry should have a logical record length less than 2048 characters. This should allow a group to contain about (2048/10) 200 users.

    I have tested this for group entries for of 819 characters or about 80 users.
