Hi Petr,
Yes definitely using IPA 3.0 packages as per the package details provided
earlier.
Ah, I see. This was reverted in a patch for EL6. Sorry for doubting you.
To get rid of the error, since you're not afraid to modify code, you can
follow the instruction inline:
The following code is present in the replica installer script:
------------------------------------------------------------------------------------------------------------
# Try out the password
ldapuri = 'ldaps://%s' % ipautil.format_netloc(config.master_host_name)
Here, insert the line:
replman = None
try:
conn = ldap2(shared_instance=False, ldap_uri=ldapuri, base_dn='')
conn.connect(bind_dn=DN(('cn', 'directory manager')),
bind_pw=config.dirman_password,
tls_cacertfile=CACERT)
replman = ReplicationManager(config.realm_name,
config.master_host_name,
config.dirman_password)
found = False
try:
entry = conn.find_entries(u'fqdn=%s' % host, ['dn', 'fqdn'],
DN(api.env.container_host, api.env.basedn))
print "The host %s already exists on the master server.\nYou should
remove it before proceeding:" % host
print " %% ipa host-del %s" % host
found = True
except errors.NotFound:
pass
try:
(agreement_cn, agreement_dn) = replman.agreement_dn(host)
entry = conn.get_entry(agreement_dn, ['*'])
print "A replication agreement for this host already exists. It needs
to be removed. Run this on the master that generated the info file:"
print " %% ipa-replica-manage del %s --force" % host
found = True
except errors.NotFound:
pass
if found:
sys.exit(3)
except errors.ACIError:
sys.exit("\nThe password provided is incorrect for LDAP server %s" %
config.master_host_name)
except errors.LDAPError:
sys.exit("\nUnable to connect to LDAP server %s" %
config.master_host_name)
finally:
if conn and conn.isconnected():
conn.disconnect()
if replman and replman.conn:
replman.conn.unbind_s()
------------------------------------------------------------------------------------------------------------
The background to this problem is that we have 6 x IPA servers, 2 each in 3 x
DCs.
In one DC we had a problem with storage which messed up the 2 IPAs, 1 of which
was the master from which replicas were originally taken.
After promoting a good IPA box in another DC(as per
http://docs.fedoraproject.org/en-US/Fedora/15/html/FreeIPA_Guide/promoting-replica.html)
I cannot now create new replicas to replace the two which were messed up.
But when trying to install them I am getting the error "UnboundLocalError: local
variable 'replman' referenced before assignment".
Fixing the UnboundLocalError will reveal the real problem.
If you get "LDAP server on ipabox1.domain.com is not responding." again,
please check if the server is really unreachable, using:
ldapsearch -x -s one -b cn=schema -h ipabox1.domain.com

You say you are using the IPA 3.0 packages. Are you sure?
The "UnboundLocalError" should have been fixed in IPA 3.0.0 (as a side
effect of fixing https://fedorahosted.org/freeipa/ticket/2845 )
I checked the CentOS 3.5 srpm, and the fix is there. Yet it is missing
from the source you quote below.

These are IPA replicas being re-added.
I removing these replman lines in the installer script:
What do you mean by "Removing the replman lines"? Is this quote from
before or after you removed them?

However LDAP ports on the IPA master are working and accessible(checked
