Hello,

Could you please help me to understand the problem that i didn't really resolv..

I have my openldap platform which has been working well

OpenldapServer : 2.3.39 Openldapclient : RedHat 5.x with nss_ldap and pam_ldap.so release 253-51

All my servers were configured with : /etc/nsswitch.conf /etc/ldap.conf and /etc/pam.d/sshd The user authentification with ssh connection is perfect. The filter of authorisation host connection is ok too. Everything is ok.

But i've recently realized that i have a lot of TCP CLOSE_WAIT connexion from differents servers to my OpenLdapServer. These connexions are somethings like :

tcp 1 0 IP_CLIENT:44633 OPENLDAP_SERVER:389 CLOSE_WAIT 3321/crond off (0.00/0/0) tcp 1 0 IP_CLIENT:44674 OPENLDAP_SERVER:389 CLOSE_WAIT 2426/nagios off (0.00/0/0) tcp 1 0 IP_CLIENT:44956 OPENLDAP_SERVER:389 CLOSE_WAIT 4652/ntpd off (0.00/0/0) .....

And so on ..

I have ~20 TCP CLOSE_WAIT connection to OPENLDAP_SERVER I don't understand when these applications tried to connect to OPENLDAP server and why i have TCP persistent connexion.

Meanwhile, I only have SSHD configured to use pam_ldap.so ...

Someone can help me please ?!?

Thanks by advance for your answer and i m sorry about my English
