The Web Client is optimized for efficient group lookup and is recommended if you have a large AD environment.Ensure that the user is not a member of a large number of Active Directory groups.This is only applicable for AD over LDAP configuration:Reduce the base DN scope:For example:Change dc=VMware, dc=com to dc=Admins, dc=VMware, dc=comUse Global Catalog port 3268/3269 in the SSO configuration of AD over LDAP. Note: Make sure Global Catalog port is enabled on domain controller.Increase the timeout. To increase the timeout value using the vSphere Client:Click Administration > vCenter Server Settings > Timeout Setting.Set Normal Operation to 120.Set Long Operation to 500.
