NAME
       ldap_search,  ldap_search_s,  ldap_search_st,  ldap_search_ext,  ldap_search_ext_s  - Perform an LDAP
       search operation

LIBRARY
       OpenLDAP LDAP (libldap, -lldap)

SYNOPSIS
       #include <sys/types.h>
       #include <ldap.h>

       int ldap_search_ext(
              LDAP *ld,
              char *base,
              int scope,
              char *filter,
              char *attrs[],
              int attrsonly,
              LDAPControl **serverctrls,
              LDAPControl **clientctrls,
              struct timeval *timeout,
              int sizelimit,
              int *msgidp );

       int ldap_search_ext_s(
              LDAP *ld,
              char *base,
              int scope,
              char *filter,
              char *attrs[],
              int attrsonly,
              LDAPControl **serverctrls,
              LDAPControl **clientctrls,
              struct timeval *timeout,
              int sizelimit,
              LDAPMessage **res );

DESCRIPTION
       These routines are used to perform LDAP search operations.  The ldap_search_ext_s() routine does  the
       search  synchronously (i.e., not returning until the operation completes), providing a pointer to the
       resulting LDAP messages at the location pointed to by the res parameter.

       The ldap_search_ext() routine is the asynchronous version, initiating the search  and  returning  the
       message id of the operation it initiated in the integer pointed to by the msgidp parameter.

       The base parameter is the DN of the entry at which to start the search.

       The  scope  parameter  is the scope of the search and should be one of LDAP_SCOPE_BASE, to search the
       object itself, LDAP_SCOPE_ONELEVEL, to search the object's immediate children, LDAP_SCOPE_SUBTREE, to
       search  the object and all its descendants, or LDAP_SCOPE_CHILDREN, to search all of the descendants.
       Note that the latter requires the server support the LDAP Subordinates Search Scope extension.

       The filter is a string representation of the filter to apply in the search.  The string  should  con-form conform
       form  to  the  format  specified in RFC 4515 as extended by RFC 4526.  For instance, "(cn=Jane Doe)".
       Note that use of the extension requires the server to support the  LDAP  Absolute  True/False  Filter
       extension.  NULL may be specified to indicate the library should send the filter (objectClass=*).

       The  attrs  parameter  is  a  null-terminated array of attribute descriptions to return from matching
       entries.  If NULL is specified, the return of all user attributes is requested.  The description  "*"
       (LDAP_ALL_USER_ATTRIBUTES)  may  be used to request all user attributes to be returned.  The descrip-tion description
       tion "+"(LDAP_ALL_OPERATIONAL_ATTRIBUTES) may be used to request all  operational  attributes  to  be
       returned.   Note  that  this requires the server to support the LDAP All Operational Attribute exten-sion. extension.
       sion.  To request no attributes, the description "1.1" (LDAP_NO_ATTRS) should be listed by itself.

       The attrsonly parameter should be set to a non-zero value if only attribute descriptions are  wanted.
       It should be set to zero (0) if both attributes descriptions and attribute values are wanted.

       The serverctrls and clientctrls parameters may be used to specify server and client controls, respec-tively. respectively.
       tively.

       The ldap_search_ext_s() routine is the synchronous version of ldap_search_ext().

       It also returns a code indicating success or, in the case of failure, indicating the  nature  of  the
       failure of the operation.  See ldap_error(3) for details.

NOTES
       Note  that  both  read  and list functionality are subsumed by these routines, by using a filter like
       "(objectclass=*)" and a scope of LDAP_SCOPE_BASE (to emulate read) or LDAP_SCOPE_ONELEVEL (to emulate
       list).

       These  routines  may  dynamically  allocate memory. The caller is responsible for freeing such memory
       using supplied deallocation routines. Return values are contained in <ldap.h>.

       Note  that  res  parameter  of  ldap_search_ext_s()  and  ldap_search_s()  should   be   freed   with
       ldap_msgfree() regardless of return value of these functions.

DEPRECATED INTERFACES
       The   ldap_search()   routine   is  deprecated  in  favor  of  the  ldap_search_ext()  routine.   The
       ldap_search_s() and ldap_search_st() routines are deprecated in favor of the ldap_search_ext_s() rou-tine. routine.
       tine.

       Deprecated interfaces generally remain in the library.  The macro LDAP_DEPRECATED can be defined to a
       non-zero value (e.g., -DLDAP_DEPRECATED=1) when compiling program designed to use  deprecated  inter-faces. interfaces.
       faces.   It  is recommended that developers writing new programs, or updating old programs, avoid use
       of deprecated interfaces.  Over time, it is expected that documentation  (and,  eventually,  support)
       for deprecated interfaces to be eliminated.
