At present the command supports only addition of control access rigts, done
so DRS access checks can be tested. It will be expanded to deal with most
ways to modify and view a DS ACL.
Shifted commands a bit. What used to be net acl is now "net acl nt" as apposed
to this, which is "net acl ds"
./bin/net acl ds set --help
Usage: set --objectdn=objectdn --car=control right --action=[deny|allow] --trusteedn=trustee-dn
Options:
-h, --help show this help message and exit
--host=HOST LDB URL for database or target server
--car=CAR The access control right to allow or deny
--action=ACTION Deny or allow access
--objectdn=OBJECTDN DN of the object whose SD to modify
--trusteedn=TRUSTEEDN
DN of the entity that gets access
Samba Common Options:
-s FILE, --configfile=FILE
Configuration file
Credentials Options:
--simple-bind-dn=DN
DN to use for a simple bind
--password=PASSWORD
Password
-U USERNAME, --username=USERNAME
Username
-W WORKGROUP, --workgroup=WORKGROUP
Workgroup
-N, --no-pass Don't ask for a password
-k KERBEROS, --kerberos=KERBEROS
