RE: Configuring Sametime to connect to LDAP server won't let me proceed... Ben Williams 16.Jan.14 06:14 AM Lotus Notes Sametime Standard 8.5.2Windows
Don't use anonymous access. I found in earlier version that anonymous cannot see the full schema which meant that change often had to be made to wimconfig.xml manually which is far from ideal. Create a bind account on your LDAP. If it's Domino then create a person document (it doesn't need an ID) and use that as the read access the SSC needs.
If you google CWLAA6003 and "sametime" you get a few hits, maybe you should follow them?
Also you can view the SystemOut.log in the STConsoleServer JVM and the dmgr SystemOut.log. These will probably provide you with the same error as above as well as more in the exception stack.
