[Samba] NT_STATUS_NOT_SUPPORTED

Hi

My Windows folks made security changes in AD that caused my Samba server to not work with AD anymore. Clients could not authenticate to their shares using their AD credentials anymore. Looking at the Samba log I could see error so I decided to reset the Computer account and to rejoin Samba to AD again.

When I tried to join Samba to AD, "net ads join -U username", I got the following error:

[2014/04/08 09:39:48.298129,  0] libads/sasl.c:823()
  kinit succeeded but ads_sasl_spnego_krb5_bind failed: Strong authentication required
Failed to join domain: failed to connect to AD: Strong authentication required

I was able to coerce google into telling me that in order to remedy this error I need to add

"client ldap sasl wrapping = sign"

to my smb.conf file. After adding this line of code I get a new error when I try and join my AD

[2014/04/08 09:40:39.131936,  0] libads/sasl.c:823()
  kinit succeeded but ads_sasl_spnego_krb5_bind failed: NT_STATUS_NOT_SUPPORTED
Failed to join domain: failed to connect to AD: NT_STATUS_NOT_SUPPORTED

and I have not been able to persuade google to give this answer up.

I am sure Kerberos works. When I test it, "kinit sambatest at AD.TRW.COM", the test succeeds. I don't get an error. And I can view the ticket with klist.

What does the "NT_STATUS_NOT_SUPPORTED" mean and how do I remedy it?

Here is a copy of my global section:

[global]
        workgroup = ADTRW
        realm = AD.TRW.COM
        server string = SAtlZA-ZFS
        security = ADS
        log file = /var/samba/log/log.%m
        max log size = 500
        client ldap sasl wrapping = sign
        load printers = No
        local master = No
        domain master = No
        dns proxy = No
        idmap uid = 20000-800000
        idmap gid = 20000-800000
        winbind separator = +
        winbind enum users = Yes
        winbind enum groups = Yes
        winbind use default domain = Yes
