Ironport C370 Ldap Accept problems

[ALFONSO MONEO VILORIA]

Hello all,

I'm having problems using ldap queries to validate recipients from my Cisco Ironport C370.

I'm receiving permanent Warning message like this:

The query CP_LDAP.accept failed with result inquiry timed out

I need to know how C370 establish TCP sessions for each Ldap host (one session for query, one session for all queries..). Ldap administrators are seeing lots of Established TCP connections fron Ironport C370 event though I've configured "Maximum number of simultaneous connections for each host" to 10.

I've checked it running the netstat command on C370 appliance (around 20 for each).

Is this a normal behaviour?

Thanks a lot.

Best Regards,

Alfonso Moneo

Hi Alfonso,

Do you have any kind of FW on the path or built-in FW on the email server?

In regards to your other question, the ESA will mantain a number of active TCP conns to your LDAP server (6 hours or 10,000 queries, what happens first).
