ldife error



1. I'm assuming you ARE on the schema master? check

2. Basically your copy of the schema needs to "write enabled", Click Start > In the run box Paste the following, It should say "command completed successfully"

regsvr32 schmmgmt.dll

ad schema manager snapin

3. Then click Start > Run > mmc > {Enter} > when the Microsoft Management Console opens > Console > AddRemove Snap-in > Add > Active Directory Schema > Add.

AD schema manager

4. Right click "Active directory" > Operations Masters > Place a tick in "The Schema may be modified in this Domain Controller" > OK.

Modify Schema Master

5. You can now close the management console (you don't need to save it).

6. You should now be able to run your Ldife command without error.
