I have following problem:
defined class ldap-client, which install and configure ldap on _all_
nodes. there is file[/etc/nsswitch.conf]. it add 'ldap' to
nsswitch.conf
defined class winbind, which install and configure winbind on _some_
nodes. and it need also to change nsswitch.conf, adding 'winbind'
there.
i can't imaging something better than add
if tagged(winbind) {
$winbind = 'winbind'
} else {
$winbind = ''
}
in ldap-client class
and add
passwd: files <%= winbind %> ldap
to nsswithch.conf template.
can you show me the right way?
btw, my solution don't work. tagged(winbind) in ldap-client return
always false, but winbind class runs ok.
