[Pkg-samba-maint] Bug#688003: winbind4: libwbclient.so.0 no version information available

[Eric Reischer]

I can confirm this bug is, in fact, still relevant.  While the message 
itself is seemingly harmless, 'pam_winbind' and 'wbinfo' both fail to 
work when connecting to a local samba4 domain controller, ostensibly 
because of this error.  'wbinfo -p' to a running samba server returns an 
error, and pam_winbind fails to authenticate users with errors hinting 
at an inability to connect to the winbind daemon.  Curiously, 'getent 
passwd' with winbind set up in nsswitch.conf still works and returns all 
users in active directory; it's just auth and the wbinfo utility that 
are broken by this.

I downloaded the Debian source package for the v4 tree 
(4.0.0~beta2+dfsg1-3.2) and built it, but extracted the 
"libwbclient.so.0" file before debian/rules deleted it, and installed 
that in place of the v3.x one that is shipped in the libwbclient0 
package, and both 'pam_winbind' and 'wbinfo -p' began working as expected.
