Hi
is portmap/rpcbind and ypbind running, look like problem of RPC and
because of them is the ypbind not runing correctly.
can you verify the functionality of ypages by :
id username
ypcat passwd |grep username
getent passwd username
this should resolve the username and verify functionality of ypages
Cheers

Good morning,
we had some issue tomorow's morning - some users couldn't login to an
email system. We use ypages for distributing passwd maps, authorizing
daemon is saslauthd.
Some users logged in, some not. "Unauthorized" users made a record to
the syslog:
Nov 24 08:01:23 email1 saslauthd[10396]: DEBUG: auth_pam: pam_authenticate
failed: User not known to the underlying authentication module
Nov 24 08:01:23 email1 saslauthd[10396]: do_auth : auth failure:

Nov 24 08:01:23 email1 imap[26411]: badlogin: localhost [127.0.0.1]
plaintext username SASL(-13): authentication failure: checkpass failed
About this time +/- seconds I see in the mail log this complains of the
postfix to the cyrus's lmtp:

The username was in all 3 hosts maps, another users logged in, there is
no complains about network connections.
This worked fine for an years, but this issue happened twice within 2
weeks.
An administrators of the ypages servers don't see any problem or logs
about theirs server.
What caused this issue ? What can I do to prevent it.
Thanks and best regards
