 # Setting up ma1sd Identity Server (optional)
 
-The playbook can configure the [ma1sd](https://github.com/ma1uta/ma1sd) Identity Server for you. It is a fork of [mxisd](https://github.com/kamax-io/mxisd) which was pronounced end of life 2019-06-21.
+**⚠️Note**: ma1sd itself has also been unmaintained for years (the latest commit and release being from 2021). The role of identity servers in the Matrix specification also has an uncertain future. **We recommend not bothering with installing it unless it's the only way you can do what you need to do**. For example, certain things like LDAP integration can also be implemented via [the LDAP provider module for Synapse](./configuring-playbook-ldap-auth.md).

 ma1sd is used for 3PIDs (3rd party identifiers like E-mail and phone numbers) and some [enhanced features](https://github.com/ma1uta/ma1sd/#features). It is private by default, potentially at the expense of user discoverability.
