Maximum amount of groups

[Dario_1]

Is there a maximum amount of groups that can be created in HP-UX? Is there a Kernel Parameter that I have to change to be able to create more than 20 groups? Thank you for your help.

The answer is essentially no but limited by the number of bits in a gid_t variable. For all intents and purposes, you can have as many as you like. What you may be referring to is the number of multiple groups to which a user may belong.

you can create way more than 20. are you getting an error when you try to create one a group? Or are you getting the error assign a user to more than 20 groups?

Yes I am having the problem when I try to assign a user to more than 20 groups. Also as a matter of more info. my /etc/group is linked to logingroup. Tkx again

For 10.20

- For local file access, not using NFS, the limit is 20.
- For remote file access, using NFS, the limit is 16.


20 groups per user is still the limit at HP-UX 11.0.

Hello Dario,

take into account that some commands do NOT work correctly any more, if you are member of too many groups...
E.g. the whole bunch of PFS (Portable File System, needed for modern CD-ROMs) does only allow up to 8 groups for "root"!

Just my ???0.02,
