We've configured Nuxeo to manage users in multi-directory mode and groups from Nuxeo database only:

nuxeo.directory.type=multi
nuxeo.ldap.user.readonly=true
nuxeo.user.group.storage=multiUserSqlGroup
nuxeo.ldap.binddn=CN=queryUser,OU=Company Users,DC=mycompany,DC=koop
nuxeo.ldap.bindpassword=***********
nuxeo.ldap.defaultAdministratorId=myadministrator@mycompany.com
nuxeo.ldap.url=ldap://activedirectory.mycompany.koop:389
nuxeo.ldap.user.mapping.company=ou
nuxeo.ldap.user.mapping.email=mail
nuxeo.ldap.user.mapping.firstname=givenName
nuxeo.ldap.user.mapping.lastname=sn
nuxeo.ldap.user.mapping.password=userPassword
nuxeo.ldap.user.mapping.rdn=userPrincipalName
nuxeo.ldap.user.mapping.username=userPrincipalName
nuxeo.ldap.user.searchBaseDn=DC=mycompany,DC=koop
nuxeo.ldap.user.searchFilter=(&(objectclass=user)(userAccountControl:1.2.840.113556.1.4.803:=512))
nuxeo.ldap.user.searchScope=subtree

We can authenticate against Active Directory, even this url works:

https://mycompany.com/nuxeo/ui/#!/admin/user-group-management/user/user1@mycompany.com

But we can't search users. Active Directory search returns a result but it cant' fetch entries. Below is the trace we get:
