Explain how autodiscovery works in ipa-client-install man pages DNS Autodiscovery Client installer by default tries to search for _ldap._tcp.DOMAIN DNS SRV records for all domains that are parent to its hostname. For example, if a client machine has a hostname 'client1.lab.example.com', the installer will try to retrieve an IPA server hostname from _ldap._tcp.lab.example.com, _ldap._tcp.example.com and _ldap._tcp.com DNS SRV records, respectively. The discovered domain is then used to configure client components (e.g. SSSD and Kerberos 5 configuration) on the machine.

   When the client machine hostname is not in a subdomain of an IPA server, its  domain  can  be
   passed  with --domain option. In that case, both SSSD and Kerberos components have the domain
   set in the configuration files and will use it to autodiscover IPA servers.

   Client machine can also be configured without a DNS autodiscovery at all. When both  --server
   and  --domain  options  are  used,  client installer will use the specified server and domain
   directly. --server option accepts multiple server hostnames which can be  used  for  failover
   mechanism.  Without  DNS  autodiscovery,  Kerberos is configured with a fixed list of KDC and
   Admin servers. SSSD is still configured to either try to read domain's  SRV  records  or  the
   specified  fixed list of servers. When --fixed-primary option is specified, SSSD will not try
   to read DNS SRV record at all (see sssd-ipa(5) for details).

For FreeIPA autodiscovery to work, what SRV records must exist on the DNS server?

ipa dns-update-system-records --dry-run

When ipa-server is setup with embedded DNS (using --setup-dns ) SRV records are automatically added in IPA.

If its external DNS server, You need to add records something like this in your DNS server.

configuration on the High Availability of the FreeIPA

_ldap._tcp.example.com. 86400 IN SRV 0 100 389 ipaserver1.example.com. _kerberos._tcp.example.com. 86400 IN SRV 0 100 88 ipaserver1.example.com. _kerberos._udp.example.com. 86400 IN SRV 0 100 88 ipaserver1.example.com. _kpasswd._tcp.example.com. 86400 IN SRV 0 100 464 ipaserver1.example.com. _kpasswd._udp.example.com. 86400 IN SRV 0 100 464 ipaserver1.example.com.

After this client will auto discover IPA server which is providing LDAP & Kerberos information.

Try to run below commands on your IPA client & point resolv.conf to IPA server & IPA client

If they return your IPA servers, It can automatically figure out your IPA servers using DNS resolver

so we can safely ignore the --server option for the ipa-client-install? but the --domain and --realm are mandatory? I am sorry, I am not sure but if your client hostname is within correct domain, I think you dont need to give domain & realm.

LDAPS with FreeIPA?

I was able to figure out my issue, thanks to your good summary!

I first was able to get a ldapsearch query working with SSL/TLS by installing the IPA server's /etc/ipa/ca.crt file on my test machine. (Though for ldaps I had to turn off name verification, or it would hang for some reason.)

With Keycloak, I had to generate a keystore from the IPA server's certificate and update the configuration in /opt/jboss/keycloak/standalone/configuration/standalone-ha.xml by adding another SPA to the list of defined SPA's. Their documentation could have been a bit clearer with this part.

This got it to work with LDAPS, though for some reason it's not working with StartTLS (I thought I got it to work once, but when I restarted the container it didn't), but at least now I have an encrypted connection.

ldapsearch Fails to Connect With LDAP Server With "TLS already started" Error ldapsearch should not be initiated with ldaps and start_tls both, Use either -ZZ or use ldaps://fqdn.of.server

Try secure ldap (ldaps://)

Raw $ ldapsearch -x -H ldaps://fqdn -b "dc=example,dc=com" or start TLS

Raw $ ldapsearch -x -ZZ -h ldap://fqdn -b "dc=example,dc=com" Root Cause STARTTLS and SSL connections cannot be used at the same time.

STARTTLS is an extension to plain text communication protocols, which offers a way to upgrade a plain text connection to an encrypted (TLS or SSL) connection instead of using a separate port for encrypted communication. It is defined in http://tools.ietf.org/html/rfc2830

Directory Server Basics

Back Up & Restore The backup process takes a snapshot of the entire database and copies it to a different location. This backup can later be restored as needed. It is important to note what is different about a backup verses an export. An export just creates an LDIF file, but it does not contain the replication changelog, tombstone entries, or the replication metadata that might be present. Backups are also much faster to create and restore then trying to process a large LDIF file.

Backups are located in:

/var/log/dirsrv/slapd-INSTANCE/bak/ Backup & Restore Stopped server

OpenLDAP Software 2.4 Administrator's Guide

ldapwiki :Root DSE

To use proxied authorization, the proxy user must have:

Permission to use the LDAP Proxy Authorization Control.

Grant access to this control using an ACI with a targetcontrol list that includes the Proxy Authorization Control OID ProxiedAuthV2 (2.16.840.1.113730.3.4.18). The ACI must grant allow(read) permission to the proxy.

This calls for an ACI with a target scope that includes the entry of the proxy user binding to the directory.

Permission to proxy as the given authorization user.

This calls for an ACI with a target scope that includes the entry of the authorization user. The ACI must grant allow(proxy) permission to the proxy.

The privilege to use proxied authorization.

Add ds-privilege-name: proxied-auth to the proxy's entry.

zabbix for monitoring FreeIPA server? Here the full steps to implement his solution:

1. open with an editor on ipa server /etc/sudoers.d/zabbix and fill with:

Defaults:zabbix !requiretty zabbix ALL = (root) NOPASSWD: /usr/sbin/ipactl status

2. open with an editor an ipa server /etc/zabbix/zabbix_agentd.d/userparameter-ipa.conf and fill with: UserParameter=ipa.status,sudo /usr/sbin/ipactl status 2>&1|egrep -v "(INFO: The ipactl command was successful$|: RUNNING$)"

3. execute on ipaserver: systemctl restart zabbix-agent

4. execute on ipaserver to verify zabix-agent config: zabbix_agentd -p|grep ipa.status

5. execute on zabbix server to verify the item can be queried (Where 192.168.0.1 is the ip of the ipa server): zabbix_get -s 192.168.0.1 -k ipa.status

(The result should be an empty line!)

6. Then on the zabbix server open a new textfile template.xml and fill it with:

<zabbix_export> 4.0 2019-05-24T06:58:01Z Templates/Applications {Template IPA server application:ipa.status.regexp([^\s],1200)}=1 <recovery_mode>0</recovery_mode> <recovery_expression/> IPA service status trigger <correlation_mode>0</correlation_mode> <correlation_tag/> 0 2 0 <manual_close>0</manual_close> </zabbix_export>

7. Import the template in zabbix and add it to your ipa server.

if you forgot the —mkhomedir option, you can use authconfig authconfig --enablemkhomedir —update

There is no authconfig in RHEL 8. It was replaced by authselect.

would enable mkhomedir support in SSSD profile.

It also tells you about oddjob service.
