authconfig:tldr:8ff9c

The command authconfig --update --enableldapauth is used to configure the system to enable LDAP authentication. Here is the breakdown of the command:

• authconfig: This is the command-line utility that manages the authentication configuration on a Linux system.
• --update: This option specifies that the authentication configuration should be updated.
• --enableldapauth: This option enables LDAP authentication, indicating that LDAP (Lightweight Directory Access Protocol) will be used as a source for user authentication.

When this command is executed, it will modify the system's authentication configuration to include LDAP as an authentication method. This allows users on the system to authenticate against an LDAP server, typically used in centralized user authentication systems where user credentials are stored in a directory server such as OpenLDAP or Microsoft Active Directory.
