Configuring Connection to LDAP server

May 29, 2015 at 7:26 PM
I'm getting this error when trying to configure the LDAP connection in Global Configuration. I've tried every radio button. Has anyone else see this error?

"It may be expected if w3wp process of Central Admin has intentionally no access to the LDAP Server"

I am also facing this issue, I already added one adfs connection, now I am trying to add another LDAP connection in central admin site, it is showing below error

unable to connect to LDAP for following reason:
The server is not operational.
It may be expected if w3wp process of central admin has intentionally no access to LDAP server.

there can be thousand of causes to those generic errors.
The simplest way to move on is to try to connect to LDAP server from server running central administration using AD tools like ldif.exe or ldp.exe.
If it works in those tools (with SP farm account), it should work in central admin
