Where are UAM details stored in the WP database

I have configured several pages using your UAM plugin. All works fine, therefore thanks for this very useful plugin.

The only issue I come across is when updating users in bulk. We want to use a routine to update user details for access to pages periodically.

I have searches wp_usermeta but am unable to find where details are stored. Can you supply the table in the database were UAM details are stored per user?

Thank you!
