[Samba] To make winbindd upset and unresponsive (3.2.6)

This simple and often-suggested command to test Samba:

getent passwd

reproducibly upsets winbindd on my SLES 10 SP1 machine.  The command
does often return many results from our campus ADS.  But after it
completes -- or if the command pauses for quite some time after
showing local users -- Samba is troubled.  In five tests this
afternoon, after getent passwd,

wbinfo --ping

fails every time until I stop and restart nmd, smb and winbindd.
Usually one of the five winbindd instances shows higher resource use
than most anything else.  No one is accessing files from this machine,
if that matters, except me.

I noticed this as I had been working to understand why my ADS account
in a local (unix) group doesn't let me change files.

Samba on this machine is: Version 3.2.6-3.1-2034-SUSE-CODE10

        log level = 1
        workgroup = ADS

        logon drive = P:

        winbind separator = +
        winbind enum users = Yes
        winbind enum groups = Yes

        idmap uid = 10000-200000
        idmap gid = 10000-200000

        wins support = No
        wins server = <our wins ip>
        winbind:ignore domains = IN-ORTHO LANGLAB GEOSURVEY <and a bunch more>
        usershare allow guests = No
        usershare max shares = 100
