Routine Description:
|
||
|
||
This routine checks to see if the Credential is from a currently
|
||
active client, and references the Credential if it is valid.
|
||
|
||
The caller may optionally request that the client's Credential be
|
||
removed from the list of valid Credentials - preventing future
|
||
requests from finding this Credential.
|
||
|
||
For a client's Credential to be valid, the Credential value
|
||
must be on our list of active Credentials.
|
||
|
||
|
||
Arguments:
|
||
|
||
CredentialHandle - Points to the CredentialHandle of the Credential
|
||
to be referenced.
|
||
|
||
RemoveCredential - This boolean value indicates whether the caller
|
||
wants the logon process's Credential to be removed from the list
|
||
of Credentials. TRUE indicates the Credential is to be removed.
|
||
FALSE indicates the Credential is not to be removed.
|
||
|
||
|
||
Return Value:
|
||
|
||
NULL - the Credential was not found.
|
||
|
||
Otherwise - returns a pointer to the referenced credential.
