Master -> replica through NAT?
by Kat 21 Jun '17

21 Jun '17

Here is an odd problem (I think). I am using IPA in one environment, and want to set up a replica in another environment through natted connections. I can setup the client to the NAT server, but here is the tricky part - IPA is also DNS. So if I try to bring the DNS setup over with -- ipa-replica-install --setup-dns --forwarder=10.x.x.x --setup-ca It fails, because when it tries to lookup the master on the other side of the NAT FW, of course it resolves incorrectly. The first failure is conn-check, so even if I --skip-conncheck, it still fails since DNS will not resolve. Suggestions? -K

Expired certificates

After rebooting my CentOS 7 IdM server, pki-tomcatd is failing to start. I see this (repeated many times) in the journal: WARNING: Exception processing realm com.netscape.cms.tomcat.ProxyRealm@383171f8 background process javax.ws.rs.ServiceUnavailableException: Subsystem unavailable at com.netscape.cms.tomcat.ProxyRealm.backgroundProcess(ProxyRealm.java:137) at org.apache.catalina.core.ContainerBase.backgroundProcess(ContainerBase.java:1357) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1543) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1553) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1553) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.run(ContainerBase.java:1521) at java.lang.Thread.run(Thread.java:748) getcert list shows a number of expired certificates (which is EXTREMELY frustrating, as I thought that certmonger, which is running, was supposed to take care of these renewals): Request ID '20170306100908': status: CA_UNREACHABLE ca-error: Error 60 connecting to https://asterisk.penurio.us:8443/ca/agent/ca/profileReview: Peer certificate cannot be authenticated with given CA certificates. stuck: no key pair storage: type=NSSDB,location='/etc/pki/pki-tomcat/alias',nickname='auditSigningCert cert-pki-ca',token='NSS Certificate DB',pin set certificate: type=NSSDB,location='/etc/pki/pki-tomcat/alias',nickname='auditSigningCert cert-pki-ca',token='NSS Certificate DB' CA: dogtag-ipa-ca-renew-agent issuer: CN=Certificate Authority,O=PENURIO.US subject: CN=CA Audit,O=PENURIO.US expires: 2017-06-19 16:27:30 UTC key usage: digitalSignature,nonRepudiation pre-save command: /usr/libexec/ipa/certmonger/stop_pkicad post-save command: /usr/libexec/ipa/certmonger/renew_ca_cert "auditSigningCert cert-pki-ca" track: yes auto-renew: yes Request ID '20170306100911': status: CA_UNREACHABLE ca-error: Error 60 connecting to https://asterisk.penurio.us:8443/ca/agent/ca/profileReview: Peer certificate cannot be authenticated with given CA certificates. stuck: no key pair storage: type=NSSDB,location='/etc/pki/pki-tomcat/alias',nickname='ocspSigningCert cert-pki-ca',token='NSS Certificate DB',pin set certificate: type=NSSDB,location='/etc/pki/pki-tomcat/alias',nickname='ocspSigningCert cert-pki-ca',token='NSS Certificate DB' CA: dogtag-ipa-ca-renew-agent issuer: CN=Certificate Authority,O=PENURIO.US subject: CN=OCSP Subsystem,O=PENURIO.US expires: 2017-06-19 16:26:30 UTC eku: id-kp-OCSPSigning pre-save command: /usr/libexec/ipa/certmonger/stop_pkicad post-save command: /usr/libexec/ipa/certmonger/renew_ca_cert "ocspSigningCert cert-pki-ca" track: yes auto-renew: yes Request ID '20170306100914': status: CA_UNREACHABLE ca-error: Error 60 connecting to https://asterisk.penurio.us:8443/ca/agent/ca/profileReview: Peer certificate cannot be authenticated with given CA certificates. stuck: no key pair storage: type=NSSDB,location='/etc/pki/pki-tomcat/alias',nickname='subsystemCert cert-pki-ca',token='NSS Certificate DB',pin set certificate: type=NSSDB,location='/etc/pki/pki-tomcat/alias',nickname='subsystemCert cert-pki-ca',token='NSS Certificate DB' CA: dogtag-ipa-ca-renew-agent issuer: CN=Certificate Authority,O=PENURIO.US subject: CN=CA Subsystem,O=PENURIO.US expires: 2017-06-19 16:26:30 UTC key usage: digitalSignature,nonRepudiation,keyEncipherment,dataEncipherment eku: id-kp-serverAuth,id-kp-clientAuth pre-save command: /usr/libexec/ipa/certmonger/stop_pkicad post-save command: /usr/libexec/ipa/certmonger/renew_ca_cert "subsystemCert cert-pki-ca" track: yes auto-renew: yes Is there a published procedure to fix this?

Frequent "LDAP query timed out" in named-pkcs11
by emil.flink＠gmail.com 21 Jun '17

21 Jun '17

Hi, I am running two FreeIPA servers up-to-date on Fedora 25, ie. v4.4.4 of FreeIPA, in a small office environment. named-pkcs11 is logging quite many (~30 a day) errors like the below block: LDAP error: Timed out: while modifying(replace) entry 'idnsname=ddns.ske1.bublar.,cn=dns,dc=ipa,dc=bublar' retrying LDAP operation (modifying(replace)) on entry 'idnsname=ddns.ske1.bublar.,cn=dns,dc=ipa,dc=bublar' LDAP query timed out. Try to adjust "timeout" parameter zone ddns.ske1.bublar/IN: serial (1498025739) write back to LDAP failed I am also seeing intermittent login issues in services configured with LDAP login, which further indicates the directory server is intermittently unresponsive. However, the "errors" log for the directory server does not contain any errors. How can I further debug/troubleshoot this issue?

Replication conflict woes

Overcoming hurdles installing freeipa-server on ubuntu 17.10
by David Harvey 20 Jun '17

20 Jun '17

Hope this helps to save some of some time digging. And I know, freeipa-server on a non LTS release is daft.. apt-get install freeipa-server-trust-ad #This has been mentioned elsewhere, and it should either be a dependency OR it's absence should not break things as it currently does sudo mkdir /etc/krb5.conf.d/ #Apparently this is expected by ipa-server to have been generated by one of the kerberos packages but is not.. mkdir -p /usr/libexec/ipa sudo ln -s /usr/lib/ipa/ipa-httpd-kdcproxy /usr/libexec/ipa/ipa-httpd-kdcproxy #The last two lines are a pretty dirty hack as I couldn't work out where in the ipa-server-install the file /etc/systemd/system/apache2.service.d/ipa.conf is created or updated. This file has a bad path to ipa-httpd-kdcproxy so ideally there should be some logic to check where it is before defining a path to it.

admin account locked due to external ssh authentication attempts
by peter＠husen.dk 20 Jun '17

20 Jun '17

I manage a small FreeIPA domain that has one server that can be accessed through ssh from the internet. I occasionally find that the admin account is locked, when I try to log in to the FreeIPA admin interface (not available from the Internet), and it seems that this is due to an endless stream of incoming ssh authentication attempts for common names like "root" and "admin", and in the latter case, the authentication is forwarded to the FreeIPA server (since the user exists in the directory, I suppose), and the account gets locked out temporarily now and then due to too many failed attempts. Now, admin is not actually supposed to be able to login through ssh (or as a POSIX account in general), so I have tried to add: DenyUsers admin to sshd_config on that server to filter out these attempts, but it seems (as far as I can see in the logs) that the authentication is still tried against the FreeIPA server, before it gets blocked by sshd. What is the best way to prevent the evil bots of the Internet from locking out my admin account?

FreeIPA master and replica behind an Elastic load balancer
by ridha.zorgui＠infor.com 19 Jun '17

19 Jun '17

I set up a FreeIPA master and replica behind an elastic load balancer in AWS cloud. FreeIPA Clients will be contacting the replica and the master sever through the load balancer so the dns name used when configurting the clients is the ELB CNAME. The problem is when retreiving data and during the authentication, the SSL handshake fail as the certificate send back from the master or replica has a hostname different than the one used in the sssd. so the connection is terminated. There is a workaround which is the use reqcert=allow but this b ring a security issue with a MITM attack. another solution i found is the use SAN but i don't seem to make it right. any thought on how to solve that will be very helpful.
