“First Boot Error Failure” – „Could not connect to VMware Directory Service via LDAP. Verify VMware Directory Service is running on the appropriate system and is reachable from this host.“

Hello together,

I faced an interessting issue at the customer recently by joining the second Platform Service Controller to an existing SSO Domain. After a lot of checks i did verify the firewall logs and found some drops.

Solution: Refer to the following VMware KB KnowledgeBase articel and open the specific ports for LDAP and LDAPS.

Search for:
=> Control interface RPC for vCenter Single Sign-On(SSO)
=> RPC port for all VMCA (VMware Certificate Authority) APIs

TCP and UDP Ports required to access VMware vCenter Server, VMware ESXi and ESX hosts, and other network components (1012382)

Give a thumb up if the article helped you!
