SYNOPSIS

# include <cssm.h>

CSSM_RETURN CSSMAPI CSSM_CSP_ChangeLoginAcl
(CSSM_CSP_HANDLE CSPHandle,
const CSSM_ACCESS_CREDENTIALS *AccessCred,
const CSSM_ACL_EDIT *AclEdit)

LIBRARY

Common Security Services Manager library (cdsa$incssm300_shr.exe)

PARAMETERS

CSPHandle (input)

The module handle that identifies the Cryptographic Service Provider to perform this operation

AccessCred (input)

A pointer to the set of one or more credentials used to authenticate and validate the caller's authorization to modify the ACL controlling login sessions with the CSP. Required credentials can include zero or more certificates, zero or more caller names, and one or more samples. Traditionally a caller name has been used to establish the context of a login session. Certificates can be used for the same purpose. If certificates and/or caller names are provided as input, these must be provided as immediate values in this structure. The samples can be provided as immediate values or can be obtained through a callback function included in the AccessCred structure.

AclEdit (input)

A structure containing information that defines the edit operation. Valid operations include adding, replacing, and deleting entries in an ACL managed by the service provider. The AclEdit parameter can contain information for a new ACL entry and a handle uniquely identifying an existing ACL entry. The information controls the edit operation as follows:

Value of AclEdit.EditMode	Use of AclEdit.NewEntry and AclEdit.OldEntryHandle
CSSM_ACL_EDIT_MODE_ADD	Adds a new ACL entry to the set of ACL entries controlling login sessions with the CSP. The new ACL entry is created from the ACL entry prototype contained in `NewEntry`. `OldEntryHandle` is ignored for this `EditMode`.
CSSM_ACL_EDIT_MODE_DELETE	Deletes the ACL entry identified by `OldEntryHandle` and associated with login sessions with the CSP. `NewEntry` is ignored for this `EditMode`.
CSSM_ACL_EDIT_MODE_REPLACE	Replaces the ACL entry identified by `OldEntryHandle` and controlling login sessions with the CSP. The existing ACL is replaced based on the ACL entry prototype contained in the `NewEntry`.

When replacing an existing ACL entry, the caller must replace all items in an ACL entry. The replacement prototype includes:

Subject type and value - A CSSM_LIST structure containing a typed subject. The subject identifies the entity authorized by this ACL entry.
Delegation flag - A CSSM_BOOL value indicating whether the subject can delegate the permissions recorded in the authorization array.
Authorization array - A CSSM_AUTHORIZATIONGROUP structure defining the set of operations for which permission is granted to the subject.
Validity period - A CSSM_ACL_VALIDITY_PERIOD structure containing two elements, the start time and the stop time for which the ACL entry is valid.
ACL entry tag - A CSSM_STRING containing a user-defined value associated with the ACL entry.

DESCRIPTION

This function edits the stored ACL controlling login sessions for a Cryptographic Service Provider (CSP). The ACL is modified according to the edit mode and information provided in AclEdit.

The caller must have a login session in process and must be authorized to modify the target ACL. Caller authentication and authorization to edit the ACL is determined based on the caller-provided AccessCred.

The caller must be authorized to add, delete, or replace the ACL entries controlling login to the CSP. When adding or replacing an ACL entry, the service provider must reject the creation of duplicate ACL entries.

When adding a new ACL entry to an ACL, the caller must provide a complete ACL entry prototype. All ACL entry items, except the ACL entry Subject, must be provided as an immediate value in AclEdit.NewEntry. The ACL entry Subject can be provided as an immediate value, from a verifier with a protected data path, from an external authentication or authorization service, or through a callback function specified in AclEdit.NewEntry.Callback.

RETURN VALUE

A CSSM_RETURN value indicating success or specifying a particular error condition. The value CSSM_OK indicates success. All other values represent an error condition.

ERRORS

Errors are described in the CDSA Technical Standard.

None specific to this call.
