[Cog_rookie]

Hi all,

I am trying to add connection to the the directory server and when click on test. It says that the directory server is not responding.

I am trying to configure everything with default, so my bind DN name is o=cognos, c=ca

Version 7.4.4

Please help. I am stuck with this for days.

The Directory Server only seems to work for a while when i restart the SERVICES locates inside the SUN\MPS folder.

It works for a little while then the connection is lost again on the access manager- administration page
