Openldap server auto disconnection

["David Vu" <David.Vu@aarnet.edu.au>]

Hi,

I am trying to set up replication between a master and a slave
openldapv2.0.11 server on RH Linux, but it doesn't seem to work.
On closer inspection, telnet to the slave server on port 389 and port
636 get an immediate disconnection from the ldap daemon.

$ telnet ldaps2 389 (same for port 636)
Trying ldaps2...
Connected to ldaps2.
Escape character is '^]'.
Connection closed by foreign host.

The ldap debug log on ldaps2 confirms this:

Dec  7 19:47:10 ldaps2 slapd[4759]: daemon: new connection on 8
Dec  7 19:47:10 ldaps2 slapd[4759]: fd=8 host access from unknown
(192.94.63.10) denied.
Dec  7 19:47:10 ldaps2 slapd[4759]: daemon: closing 8

Any know why the slapd daemon decides to close the connection
immediately?  There's no firewall/ipchains in place, and I am pretty
sure ldap doesn't use hosts.allow/deny.  I've also checked my
/etc/openldap/slapd access control filters too and there's nothing in
there to close the connection.

Any help much appreciated,

David.
