Importing users and groups from different domains.

Importing users and groups from different domains.

Hello. 
In our organization we have migrated some time ago, from local domain (where i have full access and administrative rights) to cooperate domain .I want to switch our pmp from local domain to corporate.  
But the problem is that users are placed in main domain where i doesn't have rights to create any groups, and groups are in child domain.
Is there any possible way to configure and import users that are members of groups from child domain, but those users account are in parent domain ?
I tried active directory, but when im binding to child domain and selecting ou with users groups, only users from this child domain are imported.
I tried LDAP, but when im binding to parent domain only groups from parent domain are imported. 
Does pmp support such configuration (parent - child domain) ?
best regards
Kris
