LDAP connection issue

[jad]

We have an odd LDAP connection issue.

We have an x4140 server running Solaris 10 u6 (2 cpu dual core) that is an LDAP client, and is running an Oracle database.

We have an OpenLDAP Server (version openldap-2.4.13) running on Solaris 10.

The LDAP server runs happily, and everything is fine except there is a message that appears every couple of minutes in /var/adm/messages on the x4140:

"Mar 31 11:40:54 x4140 oracle[29350]: [ID 555073 user.error] tid= 1: multiple threads per connection not supported"

Having scoured the web, this has turned up in

http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libsldap/common/ns_connmgmt.c

in the setup_mt_ld function ... so this is a Solaris issue, not an Oracle or OpenLDAP issue directly, probably affecting libsldap.so.

We are using the standard Solaris LDAP libraries, and have not changed anything from any of our other clients which all work without hassle.

Question 1: Does anyone know if this is causing any problem.
Question 2: Will changing the OpenLDAP compile options fix this?
Question 3: Will copying the OpenLDAP libs onto the x4140 fix this (which i really would like to avoid, I prefer standard/supported installs)?

Any help would be appreciated.

Hmm ... OK

I'll update this thread in case some other poor slob has this problem.

We had issues with IMAP on some of our Solaris 10 u6 server (even though it has all the LDAP patches) and not on others ... the difference between the 2 servers was that we had stopped the name service cache daemon on the ones that _DIDN'T_ work.

We used to use NIS+ and nscd got in the way all the time ... now we use LDAP nscd is Essential.

I enabled it on the x4140 and the "multiple threads per connection not supported" message stopped instantly.
