The StartImpersonation abstract interface causes the underlying security infrastructure for a server role to use the supplied ImpersonationAccessToken for access checks on secured objects until either the EndImpersonation abstract interface is called or a further call to StartImpersonation is called with a new ImpersonationAccessToken. When the EndImpersonation abstract interface is called, the security infrastructure reverts to using the primary token (see [MSDN-ACCTOKENS]). The invocation of the StartImpersonation interface is the equivalent to supplying the ImpersonationAccessToken as the Token parameter to the Access Check Algorithm defined in section 22.214.171.124.
