Hello, I want to change a computer or a user SID so I've tried to use this command : > ldbedit -H ldap://<ip of samba4> -U <domain>/administrator -s sub -d 10 cn=<pc or user sid> # editing 1 records # record 1 dn: CN=admin-PC,CN=Computers,DC=sc,DC=isc84,DC=org ... *objectSid: S-1-5-21-1031258178-388409940-3248586695-1105* ... I had the following error when I've tried to change the SID (in bold) : LDAP error 53 LDAP_UNWILLING_TO_PERFORM - <00002035: samldb: objectSid must not be specified!> <> A transaction is still active in ldb context [0x2486070] on ldap://<ip of samba4> How can I do that ?
