Dynamics CRM 2011 : C# Code for Removing Assigned Security Role to a User

Security Roles are associated with Users via N:N relationship (relationship name: systemuserroles_association). So now in CRM 2011 we can use DisassociateRequest to remove programmatically user assigned security roles .

[C# Code]:

The c # code below can be used in to remove the User assigned Security Role.

public void RemoveUserSecurityRole(Guid prmUserId, Guid prmSecurityRoleId, IOrganizationService prmCrmWebService)

{

// Create new Disassociate Request object for creating a N:N link between User and Security

DisassociateRequest wod_DisassociateRequest = new DisassociateRequest ();

// Create related entity reference object for associating relationship

// we will pass (SystemUser) record reference of user for which the role is required to be removed

wod_DisassociateRequest.RelatedEntities = new EntityReferenceCollection();

wod_DisassociateRequest.RelatedEntities.Add(new EntityReference("systemuser", prmUserId));

// Create new Relationship object for System User & Security Role entity schema and assigning it

// to request relationship property

wod_DisassociateRequest.Relationship = new Relationship("systemuserroles_association");

// Create target entity reference object for associating relationship

wod_DisassociateRequest.Target = new EntityReference("role", prmSecurityRoleId);

// Passing DisassociateRequest object to Crm Service Execute method for removing Security Role to User

prmCrmWebService.Execute(wod_DisassociateRequest);

}
