VMware NSX
The LDAP menu item is dynamically hidden by the NSX UI if an LDAP server is either not configured or fails its background connectivity check.
To restore the LDAP role assignment option, verify and fix the connectivity between NSX and your LDAP server.
If the status check fails, troubleshoot the network connectivity, credentials, or certificate trust between NSX and the LDAP provider. For detailed configuration steps, refer to the NSX LDAP Identity Source Administration Guide.
