CSSM_DB_HANDLE *DbHandle)

LIBRARY

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

PARAMETERS

DLHandle (input) 

The handle that describes the add-in data storage library module used to perform this function.

DbName (input) 

The logical name for the new data store.

DbLocation (input/optional)
  

A pointer to a network address directly or indirectly identifying the location of the storage service process. If the input is NULL, the module can assume a default storage service process location. If the DbName does not distinguish the storage service process, the service cannot be performed and the operation fails.

DBInfo (input) 

A pointer to a structure describing the format/schema of each record type that will be stored in the new data store.

AccessRequest (input)
  

An indicator of the requested access mode for the data store, such as read-only or read-write.

CredAndAclEntry (input/optional)
  

A structure containing one or more credentials authorized for creating a data base and the prototype ACL entry that will control future use of the newly created key. The credentials and ACL entry prototype can be presented as immediate values or callback functions can be provided for use by the DL to acquire the credentials and/or the ACL entry interactively. If the DL provides public access for creating a data base, then the credentials can be NULL. If the DL defines a default initial ACL entry for the new data base, then the ACL entry prototype can be an empty list.

OpenParameters (input/optional)
  

A pointer to a module-specific set of parameters required to open the data store.

DbHandle (output)
  

The handle to the newly created and open data store. The value will be set to CSSM_INVALID_HANDLE if the function fails.

DESCRIPTION

This function creates and opens a new data store. The name of the new data store is specified by the input parameter DbName. The record schema for the data store is specified in the DBINFO structure. If any RecordType defined in the DBINFO structure does not have an associated parsing module, then the ModuleSubserviceUid specified for that record type must be zero.

The newly created data store is opened under the specified access mode. If user authentication credentials are required, they must be provided. Also, additional open parameters may be required and are supplied in OpenParameters. If user authentication credentials are required, they must be provided.

Authorization policy can restrict the set of callers who can create a new resource. In this case, the caller must present a set of access credentials for authorization. Upon successfully authenticating the credentials, the template that verified the presented samples identifies the ACL entry that will be used in the authorization computation. If the caller is authorized, the new resource is created.

The caller must provide an initial ACL entry to be associated with the newly created resource. This entry is used to control future access to the new resource and (since the subject is deemed to be the "Owner") exercise control over its associated ACL. The caller can specify the following items for initializing an ACL entry:

Subject 

A CSSM_LIST structure, containing the type of the subject and a template value that can be used to verify samples that are presented in credentials when resource access is requested.

Delegation flag 

A value indicating whether the Subject can delegate the permissions recorded in the AuthorizationTag. (This item only applies to public key subjects).

Authorization tag
  

The set of permissions that are granted to the Subject.

Validity period 

The start time and the stop time for which the ACL entry is valid.

ACL entry tag 

A user-defined string value associated with the ACL entry.

The service provider can modify the caller-provided initial ACL entry to conform to any innate resource-access policy that the service provider may be required to enforce. If the initial ACL entry provided by the caller contains values or permissions that are not supported by the service provider, then the service provider can modify the initial ACL appropriately or can fail the request to create the new resource. Service providers list their supported AuthorizationTag values in their Module Directory Services primary record.

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.
