int eimListDomains(char * ldapURL,
EimConnectInfo connectInfo,
unsigned int lengthOfListData,
EimList * listData,
EimRC * eimrc)
Service Program Name: QSYS/QSYEIMThe eimListDomains() function can be used to list information for a single EIM domain or list information for all EIM domains that are reachable from this platform in the network.
The list returned contains only the information that the user has authority to access.
ldap://host:port/dn
or
ldaps://host:port/dn
where:
Examples:
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;
The EimList structure contains information about the returned data. The data returned is a linked list of EimDomain structures. firstEntry is used to get to the first EimDomain structure in the linked list.
EimList structure:
typedef struct EimList
{
unsigned int bytesReturned; /* Number of bytes actually returned
by the API */
unsigned int bytesAvailable; /* Number of bytes of available data
that could have been returned by
the API */
unsigned int entriesReturned; /* Number of entries actually
returned by the API */
unsigned int entriesAvailable; /* Number of entries available to be
returned by the API */
unsigned int firstEntry; /* Displacement to the first linked
list entry. This byte offset is
relative to the start of the
EimList structure. */
} EimList;
EimDomain structure:
typedef struct EimDomain
{
unsigned int nextEntry; /* Displacement to next entry. This
byte offset is relative to the
start of this structure */
EimListData name; /* Domain name */
EimListData dn; /* Distinguished name for the domain
*/
EimListData description; /* Description */
enum EimStatus policyAssociations; /* Policy associations
attribute */
} EimDomain;
EimListData structure:
typedef struct EimListData
{
unsigned int length; /* Length of data */
unsigned int disp; /* Displacement to data. This byte
offset is relative to the start of
the parent structure; that is, the
structure containing this
structure. */
} EimListData;
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.
| EIMERR_ACCESS (1) | Insufficient access to EIM data. |
| EIMERR_NODOMAIN (24) | EIM Domain not found or insufficient access to EIM data. |
| EIMERR_DATA_CONVERSION (13) | Error occurred when converting data between code pages. |
| EIMERR_CONN_INVAL (54) | Connection type is not valid. |
| EIMERR_EIMLIST_SIZE (16) | Length of EimList is not valid. EimList must be at least 20 bytes in length. |
| EIMERR_NOT_SECURE (32) | The system is not configured to connect to a secure port. Connection type of EIM_CLIENT_AUTHENTICATION is not valid. |
| EIMERR_PARM_REQ (34) | Missing required parameter. Please check API documentation. |
| EIMERR_PROTECT_INVAL (22) | The protect parameter in EimSimpleConnectInfo is not valid. |
| EIMERR_PTR_INVAL (35) | Pointer parameter is not valid. |
| EIMERR_SPACE (41) | Unexpected error accessing parameter. |
| EIMERR_SSL_REQ (42) | The system is configured to connect to a secure port. EimSSLInfo is required. |
| EIMERR_URL_NODOMAIN (46) | URL has no domain (required). |
| EIMERR_URL_NOHOST (47) | URL does not have a host. |
| EIMERR_URL_NOTLDAP (49) | URL does not begin with ldap. |
| EIMERR_INVALID_DN (66) | Distinguished Name (DN) is not valid. |
| EIMERR_NOMEM (27) | No memory available. Unable to allocate required space. |
| EIMERR_CONN_NOTSUPP (12) |
| EIMERR_LDAP_ERR (23) | Unexpected LDAP error. %s |
| EIMERR_UNKNOWN (44) | Unknown error or unknown system state. |
