linux pam authentication mysql workbench

MySQL Enterprise Edition supports an authentication method that enables MySQL Server to use PAM (Pluggable Authentication Modules) to. PAM is an authentication framework used by Linux, FreeBSD, Solaris, and other For example, MySQL Workbench has a checkbox titled Enable Cleartext.

No proxy users. This uses PAM only to check login names and passwords. Authentication can be performed by various PAM-supported methods. Later discussion shows how to authenticate client credentials using traditional Unix passwords, and passwords in LDAP. MySQL user names are limited to 16 characters see Section 6.

Proxy users only, with PAM group mapping. For this scenario, create one or more MySQL accounts that define different sets of privileges. Ideally, nobody should connect using those accounts directly. Then define a default user authenticating through PAM that uses some mapping scheme usually based on the external PAM groups the users are members of to map all the external user names to the few MySQL accounts holding the privilege sets.

Any client who connects and specifies an external user name as the client user name is mapped to one of the MySQL accounts and uses its privileges. You can permit some users to log in directly without proxying but require others to connect through proxy accounts. You can use one PAM authentication method for some users, and another method for other users, by using differing PAM service names among your PAM-authenticated accounts.

For example, you can use the mysql-unix PAM service for some users, and mysql-ldap for others. The examples make the following assumptions. You might need to make some adjustments if your system is set up differently. Change these to correspond to the user you want to authenticate. The PAM service name corresponds to the authentication method mysql-unix or mysql-ldap in this discussion.

If so, the plugin enables logging of diagnostic messages to the standard output. Depending on how your server is started, the message might appear on the console or in the error log. These messages can be helpful for debugging PAM-related issues that occur when the plugin performs authentication. This authentication scenario uses PAM to check external users defined in terms of operating system user names and Unix passwords, without proxying.

On Linux, the mysql-unix file might look like this:. For macOS, use login rather than password-auth. The PAM file format might differ on some systems. For example, on Ubuntu and other Debian-based systems, use these file contents instead:. Here, the authentication string contains only the PAM service name, mysql-unix , which authenticates Unix passwords. Use the mysql command-line client to connect to the MySQL server as antonio.

The server should permit the connection and the following query returns output as shown:. This demonstrates that the antonio operating system user is authenticated to have the privileges granted to the antonio MySQL user, and that no proxying has occurred. This enables the password to be passed as is to PAM. A cleartext password is necessary to use the server-side PAM library, but may be a security problem in some configurations.

These measures minimize the risk:. See Section 6. This authentication scenario uses PAM to check external users defined in terms of operating system user names and LDAP passwords, without proxying. On Linux, the mysql-ldap file might look like this:. If PAM object files have a suffix different from.

Users do not connect directly through the accounts that define the privileges. Instead, they connect through a default proxy account authenticated using PAM, such that all the external users are mapped to the MySQL accounts that hold the privileges. Any user who connects using the proxy account is mapped to one of those MySQL accounts, the privileges for which determine the database operations permitted to the external user.

The procedure shown here uses Unix password authentication. Verify that antonio is a member of the root or users PAM group. Create a default proxy user '' '' that maps external PAM users to the proxied accounts:. Here, the authentication string contains the PAM service name, mysql-unix , which authenticates Unix passwords. Otherwise, the plugin cannot tell how to perform mapping from external user names to the proper proxied MySQL user names.

If your MySQL installation has anonymous users, they might conflict with the default proxy user. For more information about this issue, and ways of dealing with it, see Default Proxy User and Anonymous User Conflicts. Create the proxied accounts and grant to each one the privileges it should have:. If you do not let anyone know the passwords for these accounts, clients cannot use them to connect directly to the MySQL server.

The server authenticates the connection using the default '' '' proxy account. The resulting privileges for antonio depend on which PAM groups antonio is a member of. The following query returns output as shown:. This demonstrates that the antonio operating system user is authenticated to have the privileges granted to the developer MySQL user, and that proxying occurred through the default proxy account. These messages may be helpful for debugging PAM-related issues that occur when the plugin performs authentication.

Some messages include reference to PAM plugin source files and line numbers, which enables plugin actions to be tied more closely to the location in the code where they occur. Another technique for debugging connection failures and determining what is happening during connection attempts is to configure PAM authentication to permit all connections, then check the system log files. This technique should be used only on a temporary basis, and not on a production server.

The mysql-any-password service file causes any authentication attempt to return true, even for incorrect passwords. If an authentication attempt fails, that tells you the configuration problem is on the MySQL side. After determining what the problem is, remove the mysql-any-password PAM service file to disable any-password access.
