Eventhough we have configured idletimeout as 0 in our slapd.conf , every 5 mins slapd is closing the connection.

May 06 06:54:07 example1 slapd[4919]: conn=10016 fd=731 closed (idletimeout)
May 06 06:54:07 example1 slapd[4919]: conn=10017 fd=732 closed (idletimeout)
May 06 06:54:07 example1 slapd[4919]: conn=10018 fd=734 closed (idletimeout)
May 06 06:54:07 example1 slapd[4919]: conn=10019 fd=735 closed (idletimeout)

Why the idletimeout setting is not taking effect?
