I'm running Groupwise 8 on Sles 11. I'm wanting to configure Groupwise to use my Windows 2008 R2 Domain controller LDAP server for authentication. I'm able to make an unsecure connection via port 389 and open the GroupWise client. However when I configure it for 636, I receive an error 81 in the POA log. Anybody have any troubleshooting suggestions?
