Prevent Admiistrators from replacing the Domino Directory design

Our Help desk team have access to create/register users and groups and admiister databases. They also seem to have the unusal ability to constantly replace the Domino Directory design, through lack of thought and process. is there a way of giving them all of the acccess that they require to do their day-to-day tasks, ie user creation and deletions, yet not give them the ability to repalce the design of the directory?

Subject: Editor Access

ACL:

Editor access can create, modify and delete documents (inlcuding use of Full text index)

Designer Access can addtionally to Editor develop and create Full text indexes

Manager can addtionally to Designer change the ACL.

Still I would tend to prioritice to educate this people instead…

Subject: They can use the webadmin client

which can be tailored to only show (for example) the “Users & Groups” tab (and no other tabs) easily via ACL roles.
