While configuring Active Directory in weblogic and obtaining group membership from Database tables, after numerous configurations, deletes and restarts, when I tried configuring the virtual adapter using libovdadapterconfig.sh I ran in the following error:
Exception in thread "main" org.xml.sax.SAXParseException: <Line 28, Column 49>: XML-20190: (Fatal Error) Whitespace required.
After a lot of digging I’ve noticed that the adapterTemplate file did not have a space between the xml variables. After adding the space everything went fine.
Hope this helps you not to loose too much time on a simple mistake.
