Samba & FreeBSD

[white list]

hope to be in the right place, I'm seeking help join a FreeBSD 6.2 machine
to a ADS Windows 2008.
when I execute "net ads join -U Administrator" I get a
"/libexec/ld-elf.so.1: /usr/lib/libkrb5.so.8: Undefined symbol
"init_error_table" error message.

[global]
        dos charset = cp866
        unix charset = koi8-r
        display charset = koi8-r
        workgroup = LAB
        realm = LAB.NET
        server string = SambaServer
        security = ADS
        password server = SAFAD.LAB.NET
        log file = /var/log/samba/log.%m
        max log size = 50
        socket options = SO_RCVBUF=8192 SO_SNDBUF=8192
        logon script = %U.bat
        logon path = \\%L\Profiles\%U
        os level = 33
        preferred master = No
        local master = No
        domain master = No
        dns proxy = No
        wins server = safad.lab.net
        idmap uid = 600-20000
        winbind separator = /
        winbind enum users = Yes
        winbind enum groups = Yes
        winbind use default domain = Yes
        inherit acls = Yes
        map acl inherit = Yes
        map archive = No
        store dos attributes = Yes

this is my global configuration,
Thanks,
Augustin,
