Hi,
I'm testing the back-meta of OpenLdap 2.4.8 in order to upgrade to this
release.
My client opens a persistent LDAP connection to slapd, binds with an ordinary
account (from the local back-bdb) and begins search operations.

I notice that if a search operation results in an LDAP error (for example error
32 : No Such Object), then back-meta opens a new connection to the target
directory for the next operation, leaving the "bad" connection open.

The conn-ttl and idle-timeout parameters do not close  the "bad" connections.
These connections  remain there until the client ends its connection. 

This saturates the target servers with unused idle connections.

Is this a bug or a normal behaviour ?

I precise that The behaviour is not the same if the client binds with rootdn.

Thanks for your help
Best regards
Ali
