When we integrated AD LDAP authentication, we also saw delays logging in (several seconds). Despite specifying specific local "Host" LDAP servers, packet captures revealed traffic going to unexpected AD LDAP servers in our other datacenters. We found that globally disabling the use of LDAP referrals corrected the issue. See K17311: https://support.f5.com/csp/article/K17311

Ditto. Our logins were taking forever too. This fixed it right away.
