vCenter 6.5 and OpenLDAP - escaping comma and space in distinguished name

[JasonES]

Hi everyone.  I am trying to add an OpenLDAP identity source within a vCenter 6.5 appliance.  The DN used to connect is in the format of "Last, First".  That's a comma followed by a space.  I'm entering the information to configure the identity source in the web GUI, and nothing I have tried to do to escape the comma or space is acceptable in the setup wizard.  I've tried the typical \ character before the comma.  I've even tried it without the space, and no matter what, the wizard highlights that box in a red border and complains about the format.  I've tried quotes in various locations as well. 

Anyone have any ideas?  The documentation from VMware on this is sorely lacking.

Thanks in advance!

Does it work if you provide a DN without a comma and space?

vCenter is happy with the syntax if I do that, but then of course the LDAP server refuses the connection since the DN isn't valid.
