Entra ID objects have a SID (securityIdentifier attribute) beginning with "S-1-12-1-" However, I've found traces of other prefixes: * S-1-12-2- * S-1-12-3- * S-1-12-8- Has anyone already seen this? 🔍 Seem to be related to special Entra ID envs like the GovCloud (GCC, FedRamp...)

Curiously there isn't a single identifier in AD, but rather a handful of unique ones. There are two unique immutable IDs: ObjectID SecurityIdentifier There are many unique IDs: sAMAccountName userPrincipalName dN servicePrincipalNames proxyAddresses (maybe?)

NTAccount NA = new NTAccount(user); SecurityIdentifier SI = (SecurityIdentifier)NA.Translate(typeof(SecurityIdentifier)); string SID = SI.ToString();

hmmm, we use SecurityIdentifier to convert the LDAP binary of a SID to a readable identifier, it's odd that functionality isn't on non-Windows in .NET 5, since a Linux machine may be consuming AD-based LDAP, etc.
