[Samba] samba 3.0.23 integrating with Active Directory + Failed to set ServicePrincipalNames

[mallapadi niranjan]

Hi all

I have a linux server with RHEL 4.0 ES with Samba 3.0.23c . I am trying to
integrate it with our Windows 2003 Active directory.
our Windows domain is EXAMPLE.COM and netbios name of the server is
EXAMPLE. The hostname of our Active directory is lesl-dom.
when we are joining to the domain we are getting the following error.
##########################################################
[root at linuxads samba-3c]# /usr/local/samba-3c/bin/net ads join

Administrator's password:
Using short domain name -- EXAMPLE
Failed to set servicePrincipalNames. Please ensure that
the DNS domain of this server matches the AD domain,
Or rejoin with using Domain Admin credentials.
Disabled account for 'LINUXADS' in realm 'EXAMPLE.COM'
