This server is recorded in the client configuration as the default. In the first place the client tries to connect to the server that the client was enrolled with. This protocol uses Kerberos for authentication and keeps the session stored on the client. In other words, if you do not use the CLI interface remotely, but prefer to run IdM CLI only on servers it will be used only during client registration/enrollment.

Introduce a balancer with sticky sessions only if the tests were conducted and default configuration really does not meet the needs.Īdministrative protocol of HTTPs - This protocol is used for all administrative activity driven by IdM CLI and UI as well as client registration operations invoked during the installation of an IPA client ( ipa-client-install). The need may emerge from cases when there are a lot of chatty applications that use IdM as a back end.īut before introducing load balancer try without it and see if the load is sustained.

The LDAP connections from legacy systems, UNIXes, and applications - usually password authentication - can be load balanced if there a real need. This makes using a load balancer even less attractive. It should be noted that SSSD uses Kerberos based authentication for such LDAP connection by default. Adding a load balancer between SSSD and IdM does not add any value and rather complicates the environment. SSSD has built in timeout, retry, and failover capabilities similar to the ones described above for Kerberos. LDAP connections from legacy systems, UNIXes and applications.LDAP connections from SSSD enabled clients.

Also, if IdM acts as an LDAP back end for an application authentication, applications can connect to IdM using an LDAP driver available in the framework the application is build with. LDAP - this protocol is used by the clients to fetch identity information but also sometimes for the authentication, especially if systems that do not have the System Security Services Daemon (SSSD) are integrated with IdM. So far we have not actually seen a precedent where current implementation was not sufficient so the improvement is more to match standards and general expectations.

There were recent upstream improvements to respect priority order based on the server weights. IdM DNS server serves Service Location (SRV) records randomly, so load balancing can be achieved in this way and it is usually sufficient. If you are concerned about load on your servers use a DNS server that can serve different SRV records based on the load. It also chooses the server either based on the explicit server list configured in nf on the client or by looking up server SRV record in DNS. Kerberos’ client library has built-in timeout, retry, and failover capabilities. The summary is that it is not recommended to load balance Kerberos communication between IdM clients and IdM servers. The details are well covered in the following blog post. There are couple ways to deal with the situation. The protocol is built in such a way that load balancer will be viewed as a man in the middle. The Kerberos protocol is not good for load balancing using traditional load balancers. One part is the main authentication and ticket exchange protocol, another is related to the administrative activity, things like password change. There are actually two distinct parts of the protocol. Kerberos - this protocol is used for the authentication and ticket acquisitions. This post dives into the details and recommendations related to this subject. In the recent months I have been getting more and more questions about identity management (IdM) in Red Hat Enterprise Linux and best practices around load balancing.
