Because of a very faulty script my root's PrimaryGroupID is 101 and UniqueID is 101. I have still an access to root, I can run sudo from my admin account, but the sudo and root do not have all the necessary rights obviously.
I can read dscl output, for instance:
dscl . -read /Users/root PrimaryGroupID PrimaryGroupID: 101 dscl . -list /Users UniqueID root 101 dscl . -list /Groups PrimaryGroupID wheel 0
But I cannot change anything with dscl:
sudo dscl . -change /Users/root UniqueID 101 0 <main> attribute status: eDSPermissionError <dscl_cmd> DS Error: -14120 (eDSPermissionError)
What is interesting, when I run:
dscl . -read /Groups/wheel GroupMembership GroupMembership: root
How can I reset the UniqueID and PrimaryGroupID of the root to 0. I logged in Terminal through Mac OS X Installation DVD, I have a superuser with all the necessary rights there, but I did not figure out how to access the records of Directory Service from there.
