UNIX group limitations
While working on the security enhancements, I stumbled upon a few fundamental UNIX limitations with groups.
Group name length
- NIS: 8 characters (source)
- HPUX: 8 characters, 16 starting from HPUX 10 (source, source)
- AIX: 8 characters, 255 for AIX 5.3 and above (source)
- Debian: 16 characters (source, defined in shadow at compile-time)
- Redhat: 16 characters, 32 starting from 2005 (source, source, source)
- Active Directory: 11 or 64 characters (source unclear)
