Hey Mike,
I am currently rehosting my 10.1 M020 system to a test server and it has gone fairly well until we (myself and tech from PTC) cannot get my Ldap adapters that were rehosted from my production server (where they work fine) to work. Every time we add them to the wt,properties file and try to start WIndchill I get a LDAP Error code 49 which is supposed to be something to do with the mapcredentials file. We have rechecked the AD bind user and password multiple times and nothing seems to fix it....maybe you have had some experience with this or maybe not....we use our corporate AD as login for Windchill....
