Linux LDAP Authentication
If you have a decent number of Linux machines and you want them all to share the same authentication scheme (allow a user to login on each of the machines), what do you do?
One of the best solutions is LDAP. LDAP stands for Lightweight Directory Access Protocol and it is basically a database of user information. You can use LDAP as a global address book of sorts, and you can also use it to store user information, such as usernames and password. Getting LDAP configured on Linux can be challenging, and I have been looking for a good guide on how to do it. The problem is that setting it up is slightly different on every Linux distro, because of differences in how each distro has PAM set up. However, I have found a great guide, that makes setting up LDAP far easier. If you get authentication with LDAP working, you'll never look back.
