what is the difference between system users vs aem users vs service users

[smacdonald2008 · Accepted solution]

A normal AEM user has an account with AEM and can perform tasks - like authoring, creating pages, etc,

A System user is meant for use with special tasks like using it in code to get a session - as discussed here: Adobe Experience Manager Help | Persisting Adobe Experience Manager 6.4 JCR data using a Custom Form...

A System user is not an actual person who uses that account - but used in code as shown in that article. (That article, we show how to create a system user and perform Sling Mapping so it can be used in Java code to get a session.)

So you do not use a System user to perform AEM tasks - like logging into AEM and creating pages, and you do not use a user account to get a session as shown in the above article.

Hope that helps...
