ldap_get_option, ldap_set_option - get or set session preferences in the ldap structure.
 

SYNOPSIS

cc [ flag... ] file... -lldap [ library... ]
#include <lber.h>
#include <ldap.h>

LDAP ldap_set_option(LDAP *ld, int option, void *optdata[]);

LDAP ldap_get_option(LDAP *ld, int option, void optdata[]);

DESCRIPTION

These functions provide an LDAP structure with access to session preferences. The ldap_get_option() function gets session preferences from the LDAP structure. The ldap_set_option() function sets session preferences in the LDAP structure.

The ld parameter specifies the connection handle, a pointer to an LDAP structure that contains information about the LDAP server connection. The option parameter specifies the name of the option to be read or modified. The optdata parameter serves as a pointer to the value of the option that you set or get.  

PARAMETERS

The following values can be specified for the option parameter:

LDAP_OPT_API_INFO

Retrieves basic information about the LDAP API implementation at execution time. The data type for the optdata parameter is (LDAPAPIInfo *). This option is READ-ONLY and cannot be set.

LDAP_OPT_DEREF

Determines how aliases are handled during a search. The data type for the optdata parameter is (int *). The following values can be specified for the optdata parameter:

LDAP_DEREF_NEVER

Specifies that aliases are never dereferenced.

LDAP_DEREF_SEARCHING

Specifies that aliases are dereferenced when searching under the base object, but not when finding the base object.

LDAP_DEREF_FINDING

Specifies that aliases are dereferenced when finding the base object, but not when searching under the base object.

LDAP_DEREF_ALWAYS

Specifies that aliases are always dereferenced when finding the base object and searching under the base object.

LDAP_OPT_SIZELIMIT

Specifies the maximum number of entries returned by the server in search results. The data type for the optdata parameter is (int *). Setting the optdata parameter to LDAP_NO_LIMIT removes any size limit enforced by the client.

LDAP_OPT_TIMELIMIT

Specifies the maximum number of seconds spent by the server when answering a search request. The data type for the optdata parameter is (int *). Setting the optdata parameter to LDAP_NO_LIMIT removes any time limit enforced by the client.

LDAP_OPT_REFERRALS

Determines whether the client should follow referrals. The data type for the optdata parameter is (int *). The following values can be specified for the optdata parameter:

LDAP_OPT_ON

Specifies that the client should follow referrals.

LDAP_OPT_OFF

Specifies that the client should not follow referrals.

By default, the client follows referrals.

LDAP_OPT_RESTART

Determines whether LDAP I/O operations are automatically restarted if aborted prematurely. It can be set to one of the constants LDAP_OPT_ON or LDAP_OPT_OFF.

LDAP_OPT_PROTOCOL_VERSION

Specifies the version of the protocol supported by the client. The data type for the optdata parameter is (int *). The version LDAP_VERSION2 or LDAP_VERSION3 can be specified. If no version is set, the default version LDAP_VERSION2 is set. To use LDAP v3 features, set the protocol version to LDAP_VERSION3.

LDAP_OPT_SERVER_CONTROLS

Specifies a pointer to an array of LDAPControl structures that represent the LDAP v3 server controls sent by default with every request. The data type for the optdata parameter for ldap_set_option() is (LDAPControl **). For ldap_get_option(), the data type is (LDAPControl ***).

LDAP_OPT_CLIENT_CONTROLS

Specifies a pointer to an array of LDAPControl structures that represent the LDAP v3 client controls sent by default with every request. The data type for the optdata parameter for ldap_set_option() is (LDAPControl **). For ldap_get_option(), the data type is (LDAPControl ***).

LDAP_OPT_API_FEATURE_INFO

Retrieves version information at execution time about extended features of the LDAP API. The data type for the optdata parameter is (LDAPAPIFeatureInfo *). This option is READ-ONLY and cannot be set.

LDAP_OPT_HOST_NAME

Sets the host name or a list of hosts for the primary LDAP server. The data type for the optdata parameter for ldap_set_option() is (char *). For ldap_get_option(), the data type is (char **).

LDAP_OPT_ERROR_NUMBER

Specifies the code of the most recent LDAP error that occurred for this session. The data type for the optdata parameter is (int *).

LDAP_OPT_ERROR_STRING

Specifies the message returned with the most recent LDAP error that occurred for this session. The data type for the optdata parameter for ldap_set_option() is (char *) and for ldap_get_option() is (char **).

LDAP_OPT_MATCHED_DN

Specifies the matched DN value returned with the most recent LDAP error that occurred for this session. The data type for the optdata parameter for ldap_set_option() is (char *) and for ldap_get_option() is (char **).

LDAP_OPT_REBIND_ARG

Sets the last argument passed to the routine specified by LDAP_OPT_REBIND_FN. This option can also be set by calling the ldap_set_rebind_proc() function. The data type for the optdata parameter is (void * ).

LDAP_OPT_REBIND_FN

Sets the routine to be called to authenticate a connection with another LDAP server. For example, the option is used to set the routine called during the course of a referral. This option can also be by calling the ldap_set_rebind_proc() function. The data type for the optdata parameter is (LDAP_REBINDPROC_CALLBACK *).

LDAP_OPT_X_SASL_MECH

Sets the default SASL mechanism to call ldap_interactive_bind_s(). The data type for the optdata parameter is (char * ).

LDAP_OPT_X_SASL_REALM

Sets the default SASL_REALM. The default SASL_REALM should be used during a SASL challenge in response to a SASL_CB_GETREALM request when using the ldap_interactive_bind_s() function. The data type for the optdata parameter is (char * ).

LDAP_OPT_X_SASL_AUTHCID

Sets the default SASL_AUTHNAME used during a SASL challenge in response to a SASL_CB_AUTHNAME request when using the ldap_interactive_bind_s() function. The data type for the optdata parameter is (char * ).

LDAP_OPT_X_SASL_AUTHZID

Sets the default SASL_USER that should be used during a SASL challenge in response to a SASL_CB_USER request when using the ldap_interactive_bind_s function. The data type for the optdata parameter is (char * ).

LDAP_OPT_X_SASL_SSF

A read-only option used exclusively with the ldap_get_option() function. The ldap_get_option() function performs a sasl_getprop() operation that gets the SASL_SSF value for the current connection. The data type for the optdata parameter is (sasl_ssf_t * ).

LDAP_OPT_X_SASL_SSF_EXTERNAL

A write-only option used exclusively with the ldap_set_option() function. The ldap_set_option() function performs a sasl_setprop() operation to set the SASL_SSF_EXTERNAL value for the current connection. The data type for the optdata parameter is (sasl_ssf_t * ).

LDAP_OPT_X_SASL_SECPROPS

A write-only option used exclusively with the ldap_set_option(). This function performs a sasl_setprop(3SASL) operation for the SASL_SEC_PROPS value for the current connection during an ldap_interactive_bind_s() operation. The data type for the optdata parameter is (char * ), a comma delimited string containing text values for any of the SASL_SEC_PROPS that should be set. The text values are:

noanonymous

Sets the SASL_SEC_NOANONYMOUS flag

nodict

Sets the SASL_SEC_NODICTIONARY flag

noplain

Sets the SASL_SEC_NOPLAINTEXT flag

forwardsec

Sets the SASL_SEC_FORWARD_SECRECY flag

Sets the SASL_SEC_PASS_CREDENTIALS flag

minssf=N

Sets minssf to the integer value N

maxssf=N

Sets maxssf to the integer value N

maxbufsize=N

Sets maxbufsize to the integer value N

LDAP_OPT_X_SASL_SSF_MIN

Sets the default SSF_MIN value used during a ldap_interactive_bind_s() operation. The data type for the optdata parameter is (char * ) numeric string.

LDAP_OPT_X_SASL_SSF_MAX

Sets the default SSF_MAX value used during a ldap_interactive_bind_s() operation. The data type for the optdata parameter is (char * ) numeric string.

LDAP_OPT_X_SASL_MAXBUFSIZE

Sets the default SSF_MAXBUFSIZE value used during a ldap_interactive_bind_s() operation. The data type for the optdata parameter is (char * ) numeric string.
