GPO Get Inheritance Clarification

[hezekiah maina]

I'm working on Group Policy Object management as part of the GSoC project.
One of the commands I have come across is the samba-tool gpo
getinheritance <container_dn>.

I have obtained the containers using:
samba-tool gpo listcontainers {6AC1786C-016F-11D2-945F-00C04FB984F9}
(the last part being the gpo I'm obtaining containers for)
and the result was the following:
Container(s) using GPO 6AC1786C-016F-11D2-945F-00C04FB984F9
    DN: OU=Domain Controllers,DC=samdom,DC=example,DC=com

What should I pass in as my container in the get inheritance command?
