AD Import: Error! java.lang.Exception: LdapAgent.ping, javax.naming.NameNotFoundException

[Guest]

When importing users from AD, if I import dc=mydomain,dc=cloud it works
If I import ou=users,dc=mydomain,dc=cloud it doesn't work with this error:

Error! java.lang.Exception: LdapAgent.ping, javax.naming.NameNotFoundException: [LDAP: error code 32 - 0000208D: NameErr: DSID-0310028B, problem 2001 (NO_OBJECT), data 0, best match of: 'DC=mydomain,DC=cloud' ]; remaining name 'ou=users,dc=mydomain,dc=cloud'

At default, it's 'cn=users' in my memory.

When i run it as cn=users, it says sucessfully imported 0 users, 0 groups even though i'm sure there are users in the OU
Edit: after some time, it successfully imported, however, it returned to me the old AD integration I had deleted with another DC and another domain, and now I have 190 imported users and it messed everything up. Can I delete the old ones?

I don't know what happens on your side. But when it says something not found, it's because there's no such thing. Did you create an OU named 'Users'? If you want to debug it, try LdapAdmin like software. It will show you your ldap query result visually.
