When searching for an employee name we get the Error message : "Employeelookup_ldap directory is not accessible. Please alert administrator."

 Typically we see that error message pop-up for two (2) reasons.

1. The password for the AD account expired. The PassagePoint AD account should be a service account with a non-expiring password. 
2. Not enough Active Directory licenses are issued. For every client license you have there needs to be a corresponding Active Directory and Access Control integration license. So if you have three (3) client licenses but only two (2) Directory Link or Access Control licenses then when the third workstation logs onto the system then the employee lookup is blocked. Please check in PassagePoint. Home Tab\Configure System\Product Licenses. Check the bottom half of the screen and make sure the numbers are correspondingly equal.
