Hi DJ Devil,

and welcome to jOpenSim

I'm happy the problem is solved even before I could read it

For those reading here for similar connection issues, I want to point some specialities when OpenSim is on a different server than jOpenSim resides:

Most of time, the firewall port for MySQL (usually 3306) is closed for external connections. Since in this case jOpenSim needs to connect from outside, be sure to have this port opened.
Database users in MySQL are often created by default in the format username@localhost. jOpenSim will not be able to connect with this username to OpenSim even if the MySQL port is opened. So if you use the username from OpenSim for jOpenSim, be sure to duplicate this user in the format username@host-of-jOpenSim or username@ip-address-of-jOpenSim.
jOpenSim needs SELECT, UPDATE and INSERT privileges for many tables in OpenSim's database. So ensure, these privileges are set for this user.

I hope, I will find some time once to write a complete list about what privileges are required for which table, so security fanatics can keep the access as limited as possible

Also I have some OpenSim module in mind for a futuring version of jOpenSim, so that opening the MySQL port for jOpenSim will not be necessary anymore - allthough I have to admit, that this is not my highest priority at the moment.

As to your question about pwd sync: currently this is not implemented yet anywhere. But this could be solved with a plugin I would have to create (or maybe even add it to the current jOpenSimRegister-plugin?). It's definately worth to think more about it
