I recieve the same error, I logged in from multiple computers to the SQL server and I get the same error even though from each computer the username password and selecting the database works...
Code:
<?xml version="1.0">
<server>
<world>
<shortname>poh</shortname>
<longname>Portal of Hate</longname>
<!-- Only specify these two if you really think you need to. -->
<!--<address>Serving Machines IP</address>-->
<!--<localaddress>127.0.0.1</localaddress>-->
<!-- Loginserver information. -->
<loginserver>
<host>eqemulator.net</host>
<port>5998</port>
<account></account>
<password></password>
</loginserver>
<locked/>
<!-- Sets the shared key used by zone/launcher to connect to world -->
<key>********</key>
<!-- Enable and set the port for the HTTP service. -->
<http port="9080" enabled="true" mimefile="mime.types" />
</world>
<!-- Database configuration, replaces db.ini. -->
