Error connecting to an external server OpenLDAP

I put on Rancher host certificate


Launched Rancher database and certificate

sudo docker run -d --volumes-from rancher-data --restart=always -p 8080:8080 -v /etc/ssl/cert.crt:/ca.crt rancher/server:v0.44.0

Start scan logs

docker logs 7da2dadf2412

I got a line with an error

2015-11-05 12:59:32,274 ERROR [:] [] [] [] [tp1463411100-14] [i.a.a.i.l.LdapIdentitySearchProvider] Cannot locate user information for (sAMAccountName=cn=administrator***,dc=ldap***,dc=pand***,dc=biz)

Please tell me what this could mean?

Is Rancher working with OpenLDAP?

As I understand the default scheme AD. OpenLDAP has a different scheme. Advise me please what scheme to use for OpenLDAP?
