Deletes a claim type mapping rule for a security token service (STS) identity provider.

Remove-SPClaimTypeMapping [-Identity] <SPClaimMappingPipeBind> [-TrustedIdentityTokenIssuer] <SPTrustedIdentityTokenIssuerPipeBind> [-AssignmentCollection <SPAssignmentCollection>] [-Confirm [<SwitchParameter>]] [-WhatIf [<SwitchParameter>]]

The Remove-SPClaimMapping cmdlet deletes a claim type mapping rule from a farm trust STS identity provider.


Parameter Required Type Description




Specifies the claim mapping to delete.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; or a valid name of a claim mapping rule (for example, Email); or an instance of a valid SPClaimMapping object.




Specifies the farm trust identity provider STS that contains the claim mapping rule.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; or a valid name of identity provider (for example, LiveIDSTS); or an instance of a valid SPIdentityProvider object.




Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.


Remove-SPClaimMapping "Email" | Get-SPIdentityProvider "LiveIDSTS"
