Connect MySQL to AD

To set up a SASL (Simple Authentication and Security Layer) connection with MySQL, you can follow these steps:

1. Install the Cyrus SASL library:
   • Check if the library is already installed by running the command saslauthd -v in the terminal.
   • If not installed, download and install the library from the Cyrus SASL website.
2. Configure the SASL library in the MySQL configuration file (my.cnf):
   
   • Add the following lines to the file
     [mysqld]
plugin-load-add=authentication_ldap_simple.so
plugin-load-add=authentication_ldap_sasl.so
ldap-server=ldap://ldap.example.com
ldap-port=389 
ldap-base-dn="dc=example,dc=com" 
ldap-bind-dn="cn=Manager,dc=example,dc=com" 
ldap-bind-password="password"
ldap-authentication-method=sasl
ldap-sasl-mechanisms=DIGEST-MD5
ldap-sasl-realm="example.com" 
ldap-sasl-authzid="mysql@example.com"
ldap-sasl-username="uid=%s,ou=people,dc=example,dc=com" 
ldap-sasl-secprops=none
   • Replace the values in the lines with your own LDAP server information.
3. Restart the MySQL server.
4. Create a SASL user mapping in MySQL:
   • Connect to the MySQL server and run the following command:
     CREATE USER ‘sasluser’@’%’ IDENTIFIED WITH authentication_ldap_sasl;
   • Replace sasluser with the username you want to use for SASL authentication.
5. Test the SASL connection:
   • Connect to the MySQL server using the SASL user:
     mysql -u sasluser -h localhost -p
     mysql -u sasluser -h IP -p -P 3006
     -h – host
     -p – password
     -P – port number
   • Enter the SASL user’s password when prompted.
   • If the connection is successful, you should be able to run MySQL commands as usual.
