[LON-CAPA-admin] Changing SSN to PID

I don't believe so, if I remeber correctly, the auto-enrollement
manager is written with the assumption that usernames might change but
student numbers don't.

this file
/home/httpd/lonUsers/domain/ids.db
does ID->username mapping

and each student has an id stored in 

/home/httpd/lonUsers/domain/u/s/e/username/envronment.db

The key is id


Both places need to be changed.

I you want to write some code to do this inside lon-capa

&Apache::lonnet::idput($domain,%ids) is the one

$domain is the domain of the users being changed.

%ids should be a hash indexed by username with values of student ids

It'll take care of modifying both locations correctly.
