There is code in the LDAP Provisioning module[1] which you could use to do this, though the whole module is only really useful if you're going to be tying into LDAP for authentication. Perhaps the user name assigning part could be extracted out?


Cheers,

Hi folks.  I've a question that's come up on a number of my sites now.  I'd
like to be able to disallow users from selecting their own usernames, ever,
even on signup.  Instead, I want to expose various profile fields (or custom
fields via form-alter if necessary) and then base the username off of that.
E.g., first intial and last name, all lower-case.  Does anyone know of an
existing module or mechanism for that, or a common pattern that could be
turned into a module?

himself; but the moment it is divulged, it forces itself into the possession
of every one, and the receiver cannot dispossess himself of it."  -- Thomas
