Agent Authentication: DB -> LDAP Migration?

[timR]

We have an OTRS system that is working.

Customers are authenticated against LDAP.

Agents are authenticated via a mySQL database.

I would like to convert it so that agents are also authenticated via LDAP. I know I can create multiple authentication back-ends, but I would like to preserve ticket ownership. I am lucky in that my mySQL agent IDs are identical to my LDAP IDs, although I may have issues with case because all the mySQL Agent IDs are lower-case and the LDAP IDs are mixed-case.

I've searched and not really found anything on this. Is a DB -> LDAP conversion that preserves ticket ownership even possible?

I have a machine available to me that I can re-create my existing environment for testing purposes, but before I stumbled about in the dark, I thought I would ask for any guidance from anyone who has done this.
