eimRemoveAccess()--Remove EIM Access

 #include <eim.h>

 int eimRemoveAccess(EimHandle          * eim,
                     EimAccessUser      * accessUser,
                     enum EimAccessType   accessType,
                     char               * registryName,
		     EimRC              * eimrc)
 

The eimRemoveAccess() function removes the user from the EIM access group identified by the access type.

Authorities and Locks

EIM Data

Access to EIM data is controlled by EIM access groups. LDAP administrators also have access to EIM data. The access groups whose members have authority to the EIM data for this API follow:

• EIM Administrator

Parameters

eim  (Input)

The EIM handle returned by a previous call to eimCreateHandle(). A valid connection is required for this function.

accessUser  (Input)

A structure that contains the user information to remove access from.

EIM_ACCESS_LOCAL_USER	Indicates a local user name on the system that the API is run. The local user name will be converted to the appropriate access id for this system.
EIM_ACCESS_KERBEROS	Indicates a kerberos principal. The kerberos principal will be converted to the appropriate access id. For example, petejones@therealm will be converted to ibm-kn=petejones@threalm.

The EimAccessUser structure layout follows:

   enum EimAccessUserType {
       EIM_ACCESS_DN,
       EIM_ACCESS_KERBEROS,
       EIM_ACCESS_LOCAL_USER
   };

   typedef struct EimAccessUser
   {
       union {
           char * dn;
           char * kerberosPrincipal;
           char * localUser;
       } user;
       enum EimAccessUserType userType;
   } EimAccessUser;

accessType  (Input)

The type of access to remove. This parameter is passed by value. Valid values are:

EIM_ACCESS_ADMIN (0)	Administrative authority to the entire EIM domain.
EIM_ACCESS_REG_ADMIN (1)	Administrative authority to all registries in the EIM domain.
EIM_ACCESS_REGISTRY (2)	Administrative authority to the registry specified in the registryName parameter.
EIM_ACCESS_IDENTIFIER_ADMIN (3)	Administrative authority to all of the identifiers in the EIM domain.
EIM_ACCESS_MAPPING_LOOKUP (4)	Authority to perform mapping lookup operations.
EIM_ACCESS_CREDENTIAL_DATA (5)	Authority to retrieve credential data.

registryName  (Input)

The name of the registry to remove access from. This parameter is only used if EimAccessType is EIM_ACCESS_REGISTRY. If EimAccessType is anything other than EIM_ACCESS_REGISTRY, this parameter must be NULL.

eimrc  (Input/Output)

The structure in which to return error code information. If the return value is not 0, eimrc is set with additional information. This parameter may be NULL. For the format of the structure, see EimRC--EIM Return Code Parameter.

Return Value

The return value from the API. Following each return value is the list of possible values for the messageCatalogMessageID field in the eimrc parameter for that value.
