SYNOPSIS

Converts between Microsoft Entra ID SID and Object ID formats.

​
SYNTAX

Convert-EntraObjectIDAndSID [-Value] <String> [-ProgressAction <ActionPreference>] [<CommonParameters>]

​
DESCRIPTION

Automatically detects whether the input is a SID (S-1-12-1-…) or an Object ID (GUID) and converts it to the other format.
  • SID (S-1-12-1-…) → returns the corresponding Object ID (GUID)
  • Object ID (GUID) → returns the corresponding SID (S-1-12-1-…)

​
EXAMPLES

​

Convert-EntraObjectIDAndSID -Value "S-1-12-1-1234567890-987654321-1122334455-5544332211"
Converts the given SID to its corresponding Object ID (GUID).

​
EXAMPLE 2

Convert-EntraObjectIDAndSID -Value "a1b2c3d4-e5f6-7890-abcd-ef1234567890"
Converts the given Object ID to its corresponding SID.

​
EXAMPLE 3

"S-1-12-1-1234567890-987654321-1122334455-5544332211", "a1b2c3d4-e5f6-7890-abcd-ef1234567890" | Convert-EntraObjectIDAndSID

NOTES

Entra ID uses a specific SID format: S-1-12-1-{4 UInt32 components derived from the GUID bytes}. This conversion is bijective: SID <-> ObjectID. https://ps365.clidsys.com/docs/commands/Convert-EntraObjectIDAndSID
