Configure Kerberos Authentication for pgAdmin4¶
To configure Kerberos authentication, you must set your Kerberos Server and generate the kinit ticket on the client. To enable the Kerberos authentication for pgAdmin, you must configure the Kerberos settings in config_local.py or config_system.py (see the config.py documentation) on the system where pgAdmin is installed in Server mode. You can copy these settings from config.py file and modify the values for the following parameters.
The default value for this parameter is internal. To enable Kerberos authentication, you must include kerberos in the list of values for this parameter. you can modify the value as follows:
Specify value to True if you want to automatically create a pgAdmin user corresponding to the kerberos user credentials. Please note that password is not stored in the pgAdmin database.
Specify the name of pgAdmin webserver hostname. Please note that if it is not set, it will take the value of default_server parameter.
Keytab file for HTTP Service¶
Generate the Keytab file for the HTTP service principal and copy it to the pgAdmin webserver machine. Ensure that the operating system user owning the pgAdmin webserver is the owner of this file and should be accessible by that user.
Please note that either you should set default_keytab_name parameter in krb5.conf file or the environment variable KRB5_KTNAME. If not set then explicitly set KRB_KTNAME to the location of your Keytab file in the config_local.py or config_system.py file.
Apache HTTPD Configuration¶
If the pgAdmin server is under the Apache Server, then you need to add the following parameters in Directory directive of Apache HTTPD Configuration:
Browser settings to configure Kerberos Authentication¶
You need to do the browser settings on the client machine to use the Spnego/Kerberos.
For Mozilla Firefox
Open the low level Firefox configuration page by loading the about:config page.
In the Search text box, enter: network.negotiate-auth.trusted-uris
Double-click the network.negotiate-auth.trusted-uris preference and enter the hostname or the domain of the web server that is protected by Kerberos HTTP SPNEGO. Separate multiple domains and hostnames with a comma.
For Google Chrome
Open the Control Panel to access the Internet Options dialog.
Select the Security tab.
Select the Local Intranet zone and click the Sites button.
Make sure that the first two options, Include all local (intranet) sites not listed in other zones and Include all sites that bypass the proxy server are checked.
Click Advanced and add the names of the domains that are protected by Kerberos HTTP SPNEGO, one at a time, to the list of websites. For example, myhost.example.com. Click Close.
Click OK to save your configuration changes.
For Linux or MacOS:
Add the –auth-server-whitelist parameter to the google-chrome command. For example, to run Chrome from a Linux prompt, run the google-chrome command as follows:
google-chrome --auth-server-whitelist = "hostname/domain"
