Description Adam Jackson 2011-11-17 17:44:52 UTC
Description of problem:

	/lib/libpthread.so.0
[ajax@f17 ~]$ ldd -r -u /usr/lib/libsmbclient.so.0 
     26483:	/usr/lib/libsmbclient.so.0: error: relocation error: symbol krb5_locate_kdc, version krb5_3_MIT not defined in file libkrb5.so.3 with link time reference (continued)
symbol krb5_locate_kdc, version krb5_3_MIT not defined in file libkrb5.so.3 with link time reference	(/usr/lib/libsmbclient.so.0)
Unused direct dependencies:
	linux-gate.so.1
[ajax@f17 ~]$ rpm -q libsmbclient krb5-libs
libsmbclient-3.6.1-75.fc17.i686
krb5-libs-1.10-0.fc17.alpha1.0.i686

Consequently, F17 builds that link against libsmbclient will fail because not all symbols resolve.

Comment 1 Kevin Kofler 2011-11-20 04:12:17 UTC
… or they'll succeed, but without SMB support. :-/

xine-lib fails to detect libsmbclient because of this and just proceeds to build without it, though the file list in the RPM is strict enough so the missing plugin will fail the build.

Either way, this is going to break a lot of things.

Comment 2 Adam Jackson 2011-11-21 17:38:31 UTC
samba-3.6.1-76.fc17 is a rebuild without this symbol:

http://koji.fedoraproject.org/koji/taskinfo?taskID=3530245

samba's configure magic checks for this symbol and compiles without it if it's not present, but that's probably a loss of functionality.  Simo assures me it's being investigated, but I'm leaving this bug open in the meantime until a proper fix is found.

Comment 3 Andreas Schneider 2011-11-22 12:12:05 UTC
Without it, the 'net lookup kdc <realm>' will not work. This gives the IP address of a KDC for the specified REALM.

There is no other use of this function.
