- We preload our KDC with potential user's entries with an instance
- ID of "foobar" and a pre-assigned password (which for us is a not
- so-well known secret but good enough given the headache of administering
- 15,000 new accounts each September). For new user's we have a special
- program which they run and give their pre-assigned password to. If
- they succeed in authenticating with it, then this program (which
- has a srvtab instance of frobitz.admin and appears in the admin_acl.add
- file ONLY) then does a kadm_ank to add the user with a null instance
- and a good password that the program enforces.
-
- Our nightly kerberos log audit script then generates a form letter
- for these people which is snail-mailed to them the next day as a
- confirmation that it was really them who did it. Not perfect, but
- does the job for us.
-
- MIT Athena's Moira Userreg server is pretty much the same thing.
