[Freeipa-users] RHEL5 IPA client for RHEL6.3 IPA server?

[David Summers]

I have looked back through the last year of mail archives for this list 
and haven't yet found anything on this.

I spent a day or so trying to get a RHEL6.3 server set up with several 
clients,

Clients:
RHEL 6.3 32-bit
RHEL 6.3 64-bit
RHEL 5.8 32-bit
RHEL 5.8 64-bit

So far I've been able to get the RHEL 6.3 clients to register and setup 
up as a client for RHEL 6.3 IPA server but whenever I try to install the 
ipa-client on RHEL 5.8 I just get the following error:

[root at rh5 ~]# ipa-client-install
Discovery was successful!
Hostname: rh5.summersoft
Realm: SUMMERSOFT
DNS Domain: summersoft
IPA Server: ipaserver.summersoft
BaseDN: dc=summersoft


Continue to configure the system with these values? [no]: yes
User authorized to enroll computers: admin
Synchronizing time with KDC...
Unable to sync time with IPA NTP server, assuming the time is in sync.
Password for admin at SUMMERSOFT:

Joining realm failed: SASL Bind failed Local error (-2) !
child exited with 9
Installation failed. Rolling back changes.
IPA client is not configured on this system.

In the install log:

2012-10-16 23:16:35,032 DEBUG args=/usr/sbin/ipa-join -s 
ipaserver.summersoft -b
  dc=summersoft

2012-10-16 23:16:35,032 DEBUG stderr=SASL Bind failed Local error (-2) !
child exited with 9


Is RHEL 5.8 a supported client for RHEL 6.3 IPA server?

If so, what am I doing wrong?  I tried following both the RHEL 5.8 and 
RHEL 6.3 install instructions but
nothing I have tried is working so far!

Thanks in advance for any help or pointers you can provide.
