[Samba] Unable to create principle and join domain with solaris / samba 3.5.8

Has anyone had any success using net ads join to create a new service
principal and join Active Directory using samba 3.5.8. This works fine
in 3.0.35 but I'm not able to get a working create/join with 3.5.8

In samba 3.0.35 (on a host which is already allowing kerberised
loginsvia AD), the following works:

net ads join createupn='CIFS/host.domain.com' \
createcomputer='path/to/principal/' -U myadlogin

After upgrading and restarting, samba works fine but deleting the AD
service principal and samba/private files to reconfigure, the net join

# net ads join createupn='CIFS/smbtest.uk.domain.com'
createcomputer='MITKerberos/Services' -U myadlogin
Enter myadlogin's password:
Failed to join domain: failed to precreate account in ou
MITKerberos/Services: Invalid DN syntax

The OU exists in AD (and works for earlier samba versions). Looking at
net ads join output with -d 99, it looks like the net command isn't
passing the netbios name through?

The smb.conf for this is as follows

server string = SMBTEST Samba Server
security = ADS
netbios name = SMBTEST
workgroup = AAA
interfaces = SMBTEST.uk.domain.com
bind interfaces only = Yes
log level = 3
log file = /var/samba/log/log.%m
max log size = 128

hide dot files = Yes
wide links = No
local master = No
domain master = No
preferred master = No
os level = 0

comment = Home Directories
browseable = yes
public = no
writable = yes

Anyone have any pointers on how to create principles and join AD using
3.5.8 or any ideas of relevant changes between 3.0.35 and 3.5.8 that
might explain this?
