Topic
An updated ypbind package that fixes various bugs is now available.
Description
This package provides the ypbind daemon. The ypbind daemon binds NIS
clients to a NIS domain. Systems running NIS client programs must have
ypbind running.
This updated ypbind package fixes a bug in which ypbind, if it failed to
bind to a NIS domain, failed silently without alerting the user as to the
cause of the problem. When ypbind is started, the daemon tries to connect
to a NIS domain. The ypbind init script first checks whether the DOMAINNAME
environment variable is set to a value. If it is not, it then checks
whether the NISDOMAIN environment variable is set to a value, and, if so,
sets DOMAINNAME to the same value as NISDOMAIN. Previously, however, if
both the DOMAINNAME and NISDOMAIN environment variables were unset, i.e.
had no value, then ypbind silently failed when trying to bind to a domain.
In these updated packages, ypbind prints an error message to standard error
with the reason for failure whenever it cannot bind to a domain using the
procedure detailed above.
Note: the recommended method for balancing the load on NIS servers when
multiple machines are connecting with ypbind has changed with this release.
The ypbind daemon's behavior has not changed: it still pings all NIS
servers listed in the /etc/ypbind configuration file and then binds to the
single fastest-responding server. Before, it was recommended to list all
available NIS servers in each machine's /etc/ypbind.conf configuration
file. However, because even servers under high load can respond quickly to
this ping, thus inadvertently increasing their own load, it is now
recommended for administrators to list a smaller number of available NIS
servers in each machine's ypbind.conf, and to vary this list across
machines. In this way, NIS servers are automatically load-balanced due to
not every NIS server being listed as being available to every machine.
This updated ypbind package also fixes a typo in the ypbind init script. As
a consequence, ypbind produced SELinux AVC messages because the SELinux
Boolean "allow_ypbind" was not set.
All users of ypbind are advised to upgrade to this updated package, which
resolves these issues.
