Simo. </pre> </blockquote> <pre wrap="">Looks like an authentication failure: [25/Jan/2011:15:11:29 -0500] conn=391 op=0 BIND dn="uid=kdc,cn=sysaccounts,cn=etc,dc=domain,dc=com" method=128 version=3 [25/Jan/2011:15:11:29 -0500] conn=391 op=0 RESULT err=49 tag=97 nentries=0 etime=0 [25/Jan/2011:15:11:29 -0500] conn=391 op=-1 fd=73 closed - B1 The ldappwd file on both systems look identical. I don't think that the SSL certificate comes into the equation, but I have no way of knowing whether it initiates TLS or not. </pre> </blockquote> <pre wrap=""> No in ipa 1.2.x the kdc is configured to use <a moz-do-not-send="true" class="moz-txt-link-freetext" href="ldap://127.0.0.1">ldap://127.0.0.1</a> with no auth. I wonder if your local DS is having problems. Can you change krb5.conf to point to the other server (maybe using <a moz-do-not-send="true" class="moz-txt-link-freetext" href="ldaps://">ldaps://</a> so as to not expose the password in the clear) and see if the krb5kdc will start that way ? Don't use this in production, just as a test to identify where the problem lies. if it turns out it is the local DS that is having issues, then we can try to force sync it again. Ah btw, on what distribution version is this? what 389-ds base version are you using ? Simo. </pre> </blockquote> So if I switch the kdc.conf to point to the other FreeIPA ldap server the krb5kdc service starts up without any problems. I was just about to force a sync when I noticed this in the error log on the working ldap server (lets call it ipserver2): <tt>[17/Jan/2011:10:24:33 -0500] NSMMReplicationPlugin - agmt="cn=meToipaserver1.domain.com636" (ipaserver1:636): Succesfully bound cn=replication manager,cn=config to consumer, but password has expired on consumer.</tt> This is the earliest record I have on the ldap replica without going to tape. So it appears that the replica password has expired. So I have this problem. ipaserver1 is used as my winsync server, but I can not use it to start krb5kdc. ipaserver2 has a working ldap server, but is not synchronizing with the winsync master. If I fix the password expiration issue, is it going to break ipaserver2?\ </blockquote> See here for information about how to make the repl manager password not expire - <a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/8.2/html-single/Administration_Guide/index.html#Creating_the_Supplier_Bind_DN_Entry">http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/8.2/html-single/Administration_Guide/index.html#Creating_the_Supplier_Bind_DN_Entry</a> if you fix the password expiration issue, it should not break anything </blockquote> So it looks like the replication password issue was a red herring as far as the kerberos is concerned. I issued the command "ipa-replica-manage synch ipaserver1.domain.com" from the working ldap replica and no longer get password expiration errors in the error logs. However, I still can not get the krb5kdc process on ipaserver1 to start when it uses the local (ldap://127.0.0.1/) LDAP database. If I perform an LDAP search of the kdc account using the Directory Manager account, both kdc entries are identical, so it does not seem to be the password for the KDC account that is preventing the krb5kdc service from starting. Could it be the service or host principals? Should I init from ipaserver2 -> ipaserver1 (Note: ipaserver1 is the winsync server)? ipaserver1: FC 11 ipa-server-1.2.2-2.fc11.i586 ipaserver2: FC10 ipa-server-1.2.2-1.fc10.i386 </body> </html>
