Having been using LDAP lookups historically, many users have ended up with multiple accounts.

I guess that they have first attempted to login with their username, and an LDAP lookup has verified their details and created an account.

Subsequently they have tried to log in with an email address (as username) and again LDAP has verified their details, and created another account.

We also have examples where users have changed names, and have ended up creating multiple accounts too (some as many as 4 accounts...)

I've seen requests for a merge tool, and I've also submitted an email to Zoho on this (no response), so now I turn to the community for help!

What is the best way to merge accounts, without losing request history etc?

I understand the manual process (move requests, delete old accounts) but its simply not feasible at the scale we need.

We are moving SDP to a Wintel platform, so we will be able to use AD integration moving forwards - but it doesn't solve the immediate issue.
