Re: Samba LDAP Failover

Hi,

Actually the only difference is the openldap client libraries version,
I do use 2.3 instead of 2.4, but using getent, as I stated before,
works...

If I do getent passwd I get, with the failure, the immediate list of
local users and, after a timeout, I get the users list from the
secondary LDAP.
I guess that nscd is working or, at least, the service is up and
running: never understood how does the system decide to use it or
not...
For what I know if I disable the service nothing changes, so that I do
not know if nscd is working or not...
If I stop the LDAP I get the failover with getent, but I have to wait
for the timeout set in ldap.conf.

I get a timeout seconds (actualy 5 secs) delay... Then the answer,
while samba waits for the timeout set in smb.conf then fails.

Ciao a grazie!
