I'm not sure what you mean by this bug. Are you reporting a bug against the software running on your client system, or on your server system? The libldap-2.2-7 library is not directly the cause of any hanging on the client; it is only used by the slapd server and by the ldap client applications (ldapadd, ldapmodify) that come with OpenLDAP. > There is a havy to debugging bug whith the newest libldap.

But your strace shows that all the time is spent waiting for data from the server, which sounds like a server bug. While cron is hanging, do other queries (using ldapsearch, for example) still work from this system? Can you forward us a copy of your /etc/ldap/slapd.conf? What is the exact version of slapd running on your sarge system? Your client's /etc/libnss-ldap.conf (and /etc/libpam-ldap.conf, if you use libpam-ldap) may also help. Please be sure to remove any passwords from these files before sending them to the BTS, of course. Thanks, -- Steve Langasek postmodern programmer
