`Enabling Kerberos Authentication`:index:
|
||
*****************************************
|
||
|
||
To configure Kerberos authentication, you must setup your Kerberos Server and
|
||
generate a ticket on the client using *kinit*. To enable Kerberos authentication
|
||
for pgAdmin, you must configure the Kerberos settings in *config_local.py* or
|
||
*config_system.py* (see the :ref:`config.py <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.
|
||
|
||
.. csv-table::
|
||
:header: "**Parameter**", "**Description**"
|
||
:class: longtable
|
||
:widths: 35, 55
|
||
|
||
"AUTHENTICATION_SOURCES","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:
|
||
|
||
* [‘kerberos’]: pgAdmin will use only Kerberos authentication.
|
||
|
||
* [‘kerberos’, ‘internal’]: pgAdmin will first try to authenticate the user
|
||
through kerberos. If that authentication fails, then it will return back
|
||
to the login dialog where you need to provide internal pgAdmin user
|
||
credentials for authentication."
|
||
"KERBEROS_AUTO_CREATE_USER", "Set the value to *True* if you want to
|
||
automatically create a pgAdmin user corresponding to a successfully
|
||
authenticated Kerberos user. Please note that password is not stored in the
|
||
pgAdmin database."
|
||
"KRB_APP_HOST_NAME", "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
|
||
:ref:`Apache HTTPD Configuration <server_deployment>`:
|
||
|
||
* WSGIScriptReloading On
|
||
|
||
* WSGIPassAuthorization On
|
||
|
||
|
||
Browser settings to configure Kerberos Authentication
|
||
=====================================================
|
||
|
||
You need to configure the browser settings on the client machine to use
|
||
Kerberos authentication via *SPNEGO*.
|
||
|
||
- For Mozilla Firefox
|
||
|
||
- Open the low level Firefox configuration page by entering *about:config* in
|
||
the address bar.
|
||
- 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.
|
||
- Click OK.
|
||
|
||
- For Google Chrome
|
||
|
||
- On Windows:
|
||
|
||
* 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.
|
||
|
||
- On 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:
|
||
|
||
.. code-block:: text
|
||
|
||
google-chrome --auth-server-whitelist = "hostname/domain"
|
||
|
||
|
||
PostgreSQL Server settings to configure Kerberos Authentication
|
||
===============================================================
|
||
|
||
* To connect the PostgreSQL server with Kerberos authentication, GSSAPI support
|
||
has to be enabled when PostgreSQL is built and the necessary
|
||
`configuration <https://www.postgresql.org/docs/current/gssapi-auth.html>`_
|
||
has to be in place.
|
||
|
||
* In pgAdmin you need to enable Kerberos authentication for the PostgreSQL
|
||
server by setting "Kerberos authentication" flag to True in the Server dialog.
|
||
Once it is enabled, pgAdmin will not prompt for a password and will try to
|
||
connect to the PostgreSQL server using Kerberos.
|
||
|
||
* Note that, you have to login into pgAdmin with Kerberos authentication to
|
||
then connect to PostgreSQL using Kerberos.
