Post-Upgrade Steps for Additional JNDI Adapters
If you chose to copy additional JNDI adapters from the source system to the target system in the Gather Upgrade Properties phase of the Upgrade Manager, you must configure the Windchill Web Server to authenticate against the search base of the additional JNDI adapters and then restart the Web Server.
For a complete procedure, see Update the PTC HTTP Server Configuration.
