samba - Mar 2004 - Réf. : Re: Réf. : Re: Réf. : Re: using a master ldap server and a slave ldap server

The origine of my message is a problem with my local LDAP server.

last thursday I upgraded my RH 8 with the glibc update from RedHAt, after
sometimes the LDAP server is unreachable.
In log :

Some peolple says : "It's the limit of open file number", I
verified this,
it's not  this problem.
I know, it's a HS mail, but I want to know howto resolve this.

Thanks

You can use one ldapsam with multiple server, see previous posting for the
syntax. You can also setup dedicated ldap server for samba though i dont
think that samba make a intensive call to ldap server, pam/nss_ldap yes,
but 100 (concurent) user will not that high :)

This is (open)ldap problem not samba, so better fix this problem first before
trying to configure samba. I also fighting with these problem after implementing
ldap for mailserver, many peoples has similar problem, see openldap list
archive.

You can compile ol without libwrap and use acl to restrict access, if your
ldapserver is busy enough, use RH7.3 or 8 but never upgrade the glibc. i also
has bad experience with unix domain socket too, so stick with tcp.
