    docs/idmap_rid: remove deprecated base_rid from example
    
    The base_rid option has been deprecated for some time. Specifying a
    value of 1000 (as recommended in the parameter description and example
    section) can result in failed mapping of group SIDs, where RIDs do not
    start at 1000.

    libsmb: provide authinfo domain for DFS referral auth
    
    libsmbclient uses the smbc_init->smbc_get_auth_data_fn() provided
    workgroup/domain in initial connections, but then switches to the
    default smb.conf workgroup/domain when handling DFS referrals.

    libsmb: reuse connections derived from DFS referrals
    
    [MS-DFSC] 3.2.1.1 and 3.2.1.2 states that DFS targets with the same site
    location or relative cost are placed in random order in a DFS referral
    response.
    
    libsmbclient currently resolves DFS referrals on every API call, always
    using the first entry in the referral response. With random ordering,
    libsmbclient may open a new server connection, rather than reuse an
    existing (cached) connection established in a previous DFS referred API
    call.
    
    This change sees libsmbclient check the connection cache for any of the
    DFS referral response entries before creating a new connection.
    
    This change is based on a patch by Har Gagan Sahai
    <SHarGagan at novell.com>.

    This is part two of the bugfix. Make sure we pass the IP we found to
    cli_servertime(). Hence we always pass at least one of name or IP.

    cli_connect_nb_send: don't segfault on host == NULL.
    
    The functions called futher down can cope with host == NULL.
    
    BUG: https://bugzilla.samba.org/show_bug.cgi?id=11058
    
    This is part one of the bugfix:
    This ensures that it is enough to pass one of host or address to the function.
