DIGI CM32 LDAP

Hi, I’m trying to configure LDAP authentication on console server ports.
There is only place to configure LDAP ip address, LDAP search base.
When i’m trying to authenticate on port, i’m typing corresponding login:password.
DIGI CM replying with login incorrect.

I was trying to troubleshoot, and discovered that in first place that console server sends bind request with that login (which is not admin account) and my LDAP answers with bind response - invalid credentials. Which is right.

I’m assuming that must be some global configuration for LDAP authentication, where i could configure LDAP admin account for binding

Please advise
