eimChangeDomain()--Change an EIM Domain Object

Syntax

 #include <eim.h>

 int eimChangeDomain(char               * ldapURL,
                     EimConnectInfo       connectInfo,
                     enum EimDomainAttr   attrName,
                     char               * attrValue,
                     enum EimChangeType   changeType,
                     EimRC              * eimrc)

  Service Program Name: QSYS/QSYEIM

  Default Public Authority: *USE

  Threadsafe: Yes

The eimChangeDomain() function changes an attribute for the EIM domain entry identified by ldapURL.

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

ldapURL (Input)

A uniform resource locator (URL) that contains the EIM host information. This URL has the following format:

    ldap://host:port/dn
          or
    ldaps://host:port/dn

where:

host:port is the name of the host on which the EIM domain controller is running with an optional port number.
dn is the distinguished name of the domain to change.
ldaps indicates that this host/port combination uses SSL and TLS.

Examples:

ldap://systemx:389
ldaps://systemy:636/o=ibm,c=us

connectInfo (Input)

Connect information. EIM uses ldap. This parameter provides the information required to bind to ldap.

If the system is configured to connect to a secure port, EimSSLInfo is required.

For EIM_SIMPLE connect type, the creds field should contain the EimSimpleConnectInfo structure with a binddn and password. EimPasswordProtect is used to determine the level of password protection on the ldap bind.

EIM_PROTECT_NO (0)	The clear-text password is sent on the bind.
EIM_PROTECT_CRAM_MD5 (1)	The protected password is sent on the bind. The server side must support cram-md5 protocol to send the protected password.
EIM_PROTECT_CRAM_MD5_OPTIONAL (2)	The protected password is sent on the bind if the cram-md5 protocol is supported. Otherwise, the clear-text password is sent.

For EIM_KERBEROS, the default logon credentials are used. The kerberos creds field must be NULL.

For EIM_CLIENT_AUTHENTICATION, the creds field is ignored. EimSSLInfo must be provided.

The structure layouts follow:

   enum EimPasswordProtect {
       EIM_PROTECT_NO,              
       EIM_PROTECT_CRAM_MD5,
       EIM_PROTECT_CRAM_MD5_OPTIONAL
   };
   enum EimConnectType {
       EIM_SIMPLE,
       EIM_KERBEROS,
       EIM_CLIENT_AUTHENTICATION
   };

   typedef struct EimSimpleConnectInfo 
   {
        enum EimPasswordProtect protect;
        char * bindDn;
        char * bindPw;
   } EimSimpleConnectInfo;

   typedef struct EimSSLInfo 
   {
        char * keyring;
        char * keyring_pw;
        char * certificateLabel;
   } EimSSLInfo; 

   typedef struct EimConnectInfo
   {
        enum EimConnectType type;
        union {
            gss_cred_id_t * kerberos;
            EimSimpleConnectInfo simpleCreds;
        } creds;
      EimSSLInfo * ssl;
   } EimConnectInfo;

attrName (Input)

The attribute to be updated. Valid values are:

EIM_DOMAIN_DESCRIPTION (0)

Changes the description for the EIM domain. Valid changeType is EIM_CHG (0).

EIM_DOMAIN_POLICY_ASSOCIATIONS (1)

Change the indicator for whether or not the domain supports policy associations in a mapping lookup. By default, the policy associations are not supported. Valid changeType is EIM_ENABLE (3) or EIM_DISABLE (4). This attribute is controlled by the version of the API interface, not the domain. If this attribute is enabled for the domain, it will only be checked in a mapping lookup operation if the version of the mapping lookup API that is used to access the domain supports this attribute. Start of change

EIM version 2 must be supported by the local EIM APIs to specify this attribute (see eimGetVersion()--Get EIM Version). End of change

attrValue (Input)

The new value for the attribute.

If the attribute being changed is EIM_DOMAIN_POLICY_ASSOCIATIONS, this value must be NULL.

changeType (Input)

The type of change to make. This could be add, remove, change, enable, or disable. attrName parameter indicates which type is allowed for each attribute.

eimrc (Input/Output)

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

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.
