(cached) no     checking for lber.h... (cached) no     checking for ber_scanf in -llber... (cached) no     checking for ldap_open in -lldap... (cached) no     checking for ldap_search_st... (cached) no by the way , I used --with-authldap , but it's also no use . please help me ,how can I resolve this problem ,think u very much .                                             onlyubb
