[Samba] Samba 3.0 error log

[Giovanni Romanenghi]

I have samba3.0 beta3 on solaris 8 and sunone directory server 5.1SP2

This is my smb.conf:
[global]
        workgroup = TESTIPLANET
        netbios name = samba3test
        preferred master = Yes
        domain master = Yes
        wins support = Yes
        ldap suffix = o=mydomain,c=it
        ldap machine suffix = ou=people,o=mydomain,c=it
        ldap user suffix = ou=people,o=mydomain,c=it
        ldap group suffix = ou=group,o=mydomain,c=it
        ldap admin dn = uid=sambauser,cn=config
        ldap ssl = no
        passdb backend =  ldapsam:ldap://10.10.5.160/ guest
        ldap passwd sync = yes
        encrypt passwords = yes

[test]
        comment = "Test"
        path = /tmp
        read only = No

When I try to connect to test share in the log file I receive this
error:
encode.c:472: failed assertion `LBER_VALID( ber )' 

and the share don't work.

Any idea 
Bye Giovanni
