So when I was configuring SSO for VSphere I came across some issues.
Some users can’t login and others can
Using the default port of 389 some users could login but others could not.
I could see all users login information and add them to groups but they got an error when logging in:
[code lang=text]
The authentication server returned an unexpected error:
ns0:RequestFailed: Referral. The error may be caused by a malfunctioning identity source.
[/code]
How to fix the error
When the port was changed to 3268 every thing started working.
But I want to use SSL (ldaps)
The standard port for LDAPS is 636 but again this did not work for some users.
Once I changed to 3269 it worked using LDAPS
Example line
[code lang=text]
ldaps://:3269
[/code]
