---------------------------------------------

Description of problem:

Trying to test something else, I ran into a problem when trying to have one IPA server on RHEL 6.2 and another on 6.3.   I tried both master=6.3/replica=6.2 and master=6.2/replica=6.3.   I'll have to re-run the tests to get the latter error but, I believe it was the same as the former which I have here:

I setup a RHEL 6.3 IPA Master.   Then I tried to setup a RHEL 6.2 Replica
but, the install fails.  However, during install, I do see some errors but, not
the invalid syntax ones.   Could those be from multiple re-install attempts?

### On MASTER:
# ipa-replica-prepare -p $ADMINPW --ip-address=$SLAVEIP $hostname_s.$DOMAIN

### On REPLICA:
# ipa-replica-install -U --setup-dns --forwarder=$DNSFORWARD --setup-ca -w
$ADMINPW -p $ADMINPW /dev/shm/replica-info-$hostname_s.$DOMAIN.gpg

...looked normal until the following error:

  [29/29]: configuring directory to start on boot
done configuring dirsrv.
creation of replica failed: [Errno 2] No such file or directory:
'/tmp/tmp1O5dxFipa/realm_info/ldappwd'

Your system may be partly configured.
Run /usr/sbin/ipa-server-install --uninstall to clean up.


Version-Release number of selected component (if applicable):
master=2.2.0-12 from RHEL 6.3
replica=2.1.3-9 from RHEL 6.2

How reproducible:
always

Steps to Reproduce:
On MASTER (RHEL 6.3):
1.  <setup rhel 6.3 master>
2.  ipa-replica-prepare -p $ADMINPW --ip-address=$SLAVEIP $hostname_s.$DOMAIN
On REPLICA (RHEL 6.2)
3.  sftp root@$MASTERIP:/var/lib/ipa/replica-info-$hostname_s.$DOMAIN.gpg
4.  ipa-replica-install -U --setup-dns --forwarder=$DNSFORWARD --setup-ca -w
$ADMINPW -p $ADMINPW /dev/shm/replica-info-$hostname_s.$DOMAIN.gpg

Actual results:

  [29/29]: configuring directory to start on boot
done configuring dirsrv.
creation of replica failed: [Errno 2] No such file or directory:
'/tmp/tmp1O5dxFipa/realm_info/ldappwd'

Your system may be partly configured.
Run /usr/sbin/ipa-server-install --uninstall to clean up.

Expected results:

6.2 server setup as replica of the 6.3 master.
