The EUS Sessions Keep Persistent LDAP Connections

For each user session connecting using LDAP authentication (EUS), there is one session between the database server and OID server that is left alive. In time, they tend to pile up until the OID server becomes unresponsive.
This fact can be checked using network utilities such as netstat (here on OID side):
netstat -an|grep 4031
*.4031 *.* 0 0 262144 0 LISTEN 263536 0 263536 0 ESTABLISHED 263536 0 263536 0 ESTABLISHED 263536 0 263536 0 ESTABLISHED


does not help.

The OID setting: orclLDAPconnTimeOut on OID does work, only that it cuts down all the existing connections to the OID server, hence disrupting other activities that use LDAP for whatever purpose.
