According to the Perl LDAP documentation, Net::LDAP supports specifying multiple hosts
for a simple failover method upon connect. I haven tried it myself, but I would think
that one could specify multiple hosts separated by a comma on the
$Self->{'AuthModule::LDAP::Host'} setting.
The NetLDAP FAQ also suggests a way of doing this by using the example code below:
unless ( $ldaps =
Net::LDAPS->new($ldapserverone,
port=>636,timeout=>5) )
{
$ldaps = Net::LDAPS->new($ldapservertwo,
port=>636,timeout=>20) ||
return
"Can't connect to $ldapserverone or $ldapservertwo via LDAPS: $@";
}
The problem would be if OTRS keeps the LDAP connection, in that case one would
probably have to stop apache/otrs and restart it..
