For some time now (few weeks) we have had a systemic issue with one of our applications that uses LDAP to authenticate.
We use a program called Presenter, that uses the LDAP protocol to authenticate users from Active Directory. When the users open internet explorer and go to the site it display an error message.
An unexpected error occurred.
Could not open LDAP://CN=Desktop Users, OU=_DistributionGroups,DC= domainn,DC=com
When the user gets this error message they do not get directed to the login page or anything just a white IE page with this message. The interesting thing is that if they continually "refresh" "F5" the page if this error message appears after say about 5-10 times of "refreshes" they will get to the login page.
I have found this MS KB Artical which describes symptoms we are having but I do not what to apply this fix until I have done some more troubleshooting.
If any one has any ideas as where to start any suggestions would be greatlty appreciated.
I have attached the exact screenshot of what a user will encounter when trying to access this site (internal site). LDAP-error-meesage.JPG
