## Symptoms

- `"Failed to connect to LDAP server. Please ensure that the administrator's credentials are correct and try again"` error while trying to fetch branches from a statically NATed LDAP server.

## Cause

The host representing the NATed IP address of the LDAP server is used in the: LDAP Account Unit Properties \> Objects Management \>Manage objects on field.

By hiting the fetch branches button, the Management server tries to address the LDAP server with the internal IP address instead of the public NATed IP address and therefore fails, as the internal LDAP server IP is not reachable.
