configurable keepalive setting through libldap?


since quite some time libldap enables tcp-keepalive, e.g. to detected dangling 
syncrepl connections. However the default timeout of two hours that most 
systems are using might be a bit too long for some applications (e.g. I had a 
problem lately were nscd didn't answer queries anymore because nss_ldap was 
blocking in SSL_read() while the underlying connection has been cut off). On 
the other hand messing with the system wide settings might no be a good idea 
either. On Linux it is possible to configure the keepalive settings on a per 
socket basis through the TCP_KEEP* socket options.

Would it be worth adding ldap_set_option() support for those, even if they are 
not really portable?
