After installing NW60 into a NW50 tree, where NW50 is the CA, the NW6
ifolder screen says "Can't contact LDAP server (81). I ran pkidiag and
it created the SSL certificates, port 8009 works, but imanager port 2200
TID 10070462 says export the new trusted root certificate to a file and
copy to ifolder,,,, how do I export the new certifcate???

Or do I need to uninstall CA and reinstall it on the NW6?
Thanx for your help.
