Hello,
I'm trying to upgrade samba (TPTB are going to introduce win7
workstations) on my old server (mandrake 10.0) currently running 3.0.11.
I setup a virtual machine to do some testing and I built rpms for 3.5.2
(apart from the other problems it has this one
https://bugzilla.samba.org/show_bug.cgi?id=7263) then for 3.4.7 and
finally for 3.3.12.
Each one of them has problems, the most "stable" of the three is 3.3.12.
This one seems to work fine for a machine already in the domain mapping
shares to drives, but it hangs when trying to browse the server or to
add a machine to the domain.
E.g.
[luca at localhost samba]$ smbclient -L hp
WARNING: The "printer admin" option is deprecated

I'm attaching the complete level 10 log, here's an extract at the time

Since the problems are similar for the 3 versions of samba, I suspect
that one of the old system libraries is the cause of the problem:
#ldd /usr/sbin/smbd
linux-gate.so.1 => (0xffffe000)
libldap.so.2 => /usr/lib/libldap.so.2 (0x40021000)
liblber.so.2 => /usr/lib/liblber.so.2 (0x40055000)
libgssapi_krb5.so.2 => /usr/lib/libgssapi_krb5.so.2 (0x40061000)
libkrb5.so.3 => /usr/lib/libkrb5.so.3 (0x40075000)
libk5crypto.so.3 => /usr/lib/libk5crypto.so.3 (0x400ea000)
libcom_err.so.2 => /lib/libcom_err.so.2 (0x40112000)
libresolv.so.2 => /lib/libresolv.so.2 (0x40115000)
libcups.so.2 => /usr/lib/libcups.so.2 (0x40127000)
libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0x40145000)
libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x40177000)
libnsl.so.1 => /lib/libnsl.so.1 (0x4027a000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x4028d000)
libpam.so.0 => /lib/libpam.so.0 (0x402ba000)
libacl.so.1 => /lib/libacl.so.1 (0x402c3000)
libattr.so.1 => /lib/libattr.so.1 (0x402ca000)
libcap.so.1 => /lib/libcap.so.1 (0x402ce000)
libdl.so.2 => /lib/libdl.so.2 (0x402d2000)
libpopt.so.0 => /lib/libpopt.so.0 (0x402d5000)
libtalloc.so.1 => /usr/lib/libtalloc.so.1 (0x402dd000)
libtdb.so.1 => /usr/lib/libtdb.so.1 (0x402e4000)
libwbclient.so.0 => /usr/lib/libwbclient.so.0 (0x402f0000)
libc.so.6 => /lib/tls/libc.so.6 (0x402fb000)
libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x40443000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
these come from:
openldap 2.1.25
kerberos5 1.3
e2fsprogs 1.34
cups 1.1.20
openssl 0.9.7c
glibc 2.3.3
pam 0.77
attr 2.4.14
acl 2.2.22
popt 1.8.2
sasl 2.1.15
(libtalloc, libtdb, libwbclient are the ones that come with samba 3.3.12
here).
and, minus libtalloc, libtdb and libwbclient, are the same libraries
used by the currently working 3.0.11
Any one of those seem suspect?
Bye
