I've searched this forum and checked the FAQ over at Digicomplex, but I think what I want is too specific.

The intranet I'm currently developing is to be used by several organizations, as well as a webmaster supervising the lot. I'd like one user for each organization to be able to add and modify users for his organization only. What you get is something like:

Admin (supervising all)
|
+- Subadmin organization A
| |
| +- User A1
| +- User A2
| +- ...
|
+- Subadmin organization B
| |
| +- User B1
| +- User B2
| +- ...
|
+- Subadmin organization X
| |
| +- User X1
| +- User X2
| +- ...

I hope it's clear what I'm looking for, and that it is possible in the first place.

I've tried making a separate group with admin rights to the 'modify user' config, but then the user in this group can view/edit/delete all registered users.

Thanks in advance for your help!

I'm afraid that it is a very substantial change to XOOPS, you are requiring.

Assigning admins to individual user groups is just not possible and will probably not be high on the list of future changes, sorry (this is just a guess, mind you)

I had a similar problem with my Team module, where team members should be controlled by individual team leaders, but have compromised by having an all-teams admin, who decide which members are on which teams, and team leaders, who can control the members' status and ranks. This is done with an intramodule extension to the user management with separate tables etc.

Thanks for your answer, Mithrandir. I suppose I'll have to work out another solution or code this feature myself.
