User migration from DB to LDAP - Change Username ?

[pharmmed]

Hi,

we would like to switch from local DB auhentication to LDAP. unfortunately the local usernames we used so far differ from the ones used by our LDAP and TL usermanagement doesn't allow change of user name.
We already tried changing the username and authentication method for one testuser via DB script, login and everything seems ok.
We are not sure though if this could go bad on some end of the whole application - can someone tell me if we will encounter problems when changing usernames directly in the DB or if this shouldn't be a problem?

thx
