I am compiling sendmail-8.10.1 with ldap support and it complains of undefined reference to ldap_err2string when compiling mail.local and other objects such as vacation. I did add -ldap and -lber to the link (although these objects are not listed in the libraries) and the openldap-1.2.9-5 rpm is installed on RH6.2. Where is this object ldap_err2string located? Sendmail itself did compile ok. Shelley Waltz
