I am new to using LDAP and have a few questions.

1)I have tables that I would like to export information from into LDAP. How would I do go about doing this?

2)There was an old LDAP created before the current one that my company is going to use. This LDAP already has passwords. How can I export these passwords and match them up with users from the DB I am importing into the LDAP? I was thinking I could write a query to do this?

3)What program would be best for migrating information from the db and the old LDAP into the new LDAP? TIM/TAM, IDsync, or something else?
