“Add error on entry starting on line 56: Insufficient Rights” when running LDIFDE to import the “ConfigMgr_ad_schema.ldf”

I’m trying to run the LDIFDE command-line utility to import the contents of the ConfigMgr_ad_schema.ldf file for ConfigMgr 2012 into Active Directory but it’s failing with the following:

Connecting to “DCCM12R2.FAQShopCM12R2.com”

Importing directory from file “ConfigMgr_ad_schema.ldf”

Add error on entry starting on line 56: Insufficient Rights
The server side error is: 0x5 Access is denied.
The extended server error is:
00000005: SecErr: DSID-03152610, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0

0 entries modified successfully.
An error has occurred in the program

This is the command-line I’m using which others have used successfully:
ldifde –i –f ConfigMgr_ad_schema.ldf –v –j C:\Users\CmAdmin
