Problem: | Users logging in via Citrix are receiving the following error message: The login name you specified was not found. Please use a different login name or choose Cancel to exit the application. LDAP System Exception: No LDAP Server is available for authentication. Please check the LDAP Configuration in the database. Users logging into the same database on a separate Citrix server are not receiving the error message. |
Cause: | The Citrix farm (2 or more Citrix machines) are accessed through a Load Balancer |
Fix: | Make sure that the connection between the Citrix machine and the LDAP server are routed to and from the Load Balancing server. This scenario works: Machine A sends request for LDAP login to Load Balancer, Load Balancer sends request to LDAP, LDAP replies to Load Balancer, Load Balancer replies to Machine A. This scenario does not work: Machine A sends request for LDAP login to Load Balancer, Load Balancer sends request to LDAP, LDAP replies to Machine A. This scenario does not work: Machine A sends request for LDAP login to LDAP Server, LDAP server replies to Load Balancer, Load Balancer replies to Machine A |
