Yes, the bug is actually older than that---Don't know if it's only RH
based systems (as so many things seem to work everywhere but RH and
their offshoots) or ldap.
You should be able to fix it by changing /etc/ldap.conf.  There is a
default commented line in there

#bind_policy hard

Uncomment it, change it to soft.  (On the client.)  Note this is
/etc/ldap.conf--in Fedora, if that's the client, I believe it's now
/etc/pam_ldap.conf or possibly /etc/nss_ldap.conf.  

I can't find the earlier bug at first glance, but it's FAR older than
2010, and they never bothered to fix it.

See above.  Darn, I wish I could find that older bug, so that I could go
to the newer one you mention and point out that they've been unable to
fix it for far longer than a year.  :)  (I might do it anyway)  

Grouchily yours,  (Not at you, at RH for being unable to get such a
basic thing to work--actually, at one point, Fedora changed bind_policy
to soft so that it would work, but now they're back to the broken way.)

Principal Snyder: It's fuzzy-minded liberal thinking like that 
that gets you eaten.
