I'm using OpenKM 4.0. I would like to know where OpenKM stores all the user information?
What do you mean about user information:
1- user name, password etc...
2- or all the data
Because information matters
User database
- Problems with installing OpenKM? No problemo, the solution is closer than you think.

Hard job to see all 
In openkm-ds.xml ( it's in deploy %jboss_home/server/default/deploy folder ) you've got all databases defined ( for their names you could understand what have in )
The files (blobs) are stored by default - if you've not changed the default configuration - under %Jboss_home%/repository folder structure. It's not the typical operating system structure, reason why you could not accessing directly to repository files ( blobs ) directly from your hard disk server ( you could have diferent configurations, depending first starting up and repository.xml configuration file ).

I'm looking for the place where all user names and passwords are defined. I'm not finding it on the file you said
Users are stored in hypersonic database, in openkm-ds.xml have user and pass to login to okmauth database.
And here how to browse hypersonic database only in the server browser if you've got, if not you'll must use some remote app to connect like datastudio.
