процедуры обработки опций LDAP (LDAP option handling routines)
Ошибки (Error)
On success, the functions return LDAP_OPT_SUCCESS, while they may
return LDAP_OPT_ERROR to indicate a generic option handling
error. Occasionally, more specific errors can be returned, like
LDAP_NO_MEMORY to indicate a failure in memory allocation.
