  That's good.

  It depends on what you want to do...

  What do you mean "move the users" into 389?  *What* information are you moving over?

  As background, FreeRADIUS doesn't really have "users" as such.  It has things configured in databases.  The "users" file is one such database.

  It depends on what you want to do...

  Missing WHAT?  It helps to be specific.

  The documentation in mods-available/ldap explains exactly how to put attributes into LDAP.  The "users" file documentation describes how to configure attributes in the "users" file.

  So... you should be able to take attributes from the "users" file, and put them into LDAP.  As per the documentation.  If you have a specific question, please ask that.  Right now, it's all "I tried to do stuff, and it didn't work".

  Computers don't work on hand-waving.
