Issue/Introduction

Symptoms:

When you configure your Identity Source for Single Sign-On to the Active Directory domain using a server that resolves to multiple IP addresses, you experience these symptoms:

• Logging in to VMware vRealize Automation (formerly known as VMware vCloud Automation Center) and Application Director (AppD) takes longer time
• Intermittent failures across Advanced Service Designer (ASD), AppD or VMware vRealize Automation.

Environment

VMware vCloud Automation Center for Server 6.1.x

Cause

This issue occurs when one or more of the Active Directory servers in the pool are inaccessible.

Resolution

To resolve this issue, identify which LDAP service is not accessible and remove it from the pool.

To identify which service is not accessible log in to the SSO Virtual Appliance and run this command:

nslookup server.com | grep Address | cut -f2 -d":" | xargs -I{} ping -c 1 {}

This should ping all the IPs resolved for the FQDN of the LDAP server and IPs that are not reachable. Ensure to remove unreachable servers from the pool.
