samba - Feb 2004 - Permissions on ou for net join to ADS

Hi

I have noticed the following behaviour:

If I get a kerberos ticket as a domain admin user using kinit and then do a
net join to an ADS domain, then this works fine and net ads testjoin and net
ads leave work too.

However if I do it as a user with full control on a particular ou within the
AD tree, net join gives the following:

net join "/Global Administration/Samba Servers"
[2004/02/24 14:33:48, 0] libads/ldap.c:(1072)
  Warning: ads_set_machine_sd: NT_STATUS_INVALID_PARAMETER
Using short domain name -- AD
Joined 'host1' to realm 'AD.ME.CO.UK'

net ads test join still returns ok but net ads leave returns failed to
delete host xxxx from dddddd realm ( I do a net join again it deletes the
old entry and re adds the host ok ).

It's not causing any problems as such, but I just wondered if there was any
explanation for the above behaviour as I assumed full control on an ou would
be equivlaent to domain admin within the scope of that ou.

Not quite - it does not allow us to set security descriptors.    We need
to return better errors there, but that's what is going on.  So, we
allow the join to work, but we can't remove our account on domain
leave.  (We normally modify the SD to permit exactly that).
