Hello, I have many sendmail's (8.12.2) using LDAP for "access map" and, at some moments, sendmail receive LDAP_SERVER_DOWN from libldap. LDAP server isn't DOWN and many other sendmail's are using ldap server at this same time. Tracing call from libldap => "LDAP_SERVER_DOWN" is returned from wait4msg function at libraries/libldap/result.c. It's are client or server problem ? Thank's for help, -- Luiz Henrique Duma
