While testing some workflow processes, I set up two new data collector users in ODK Aggregate (v1.4.13, Appspot). I gave them new usernames (datacoll1, datacoll2), and then clicked the "Change Password" button and gave them their own passwords (also datacoll1, datacoll2). Account type was ODK, only Data Collector role checked.
I then went to the tablet and ODK Services (on rev208 for all of the tablet pieces), settings, server settings, entered username datacoll1 and Server password datacoll1. Clicked verify user permissions, Got "Protocol Error. Please verify that the server and device are compatible."
After some testing, I determined that I could login with the username datacoll1 and the server level site admin password (not datacoll1, which was what I entered in Change Password). But now I am not clear on what password I changed with "Change password." Is it that there a server password (same for all users?) that is distinct from users' passwords? What is the password in "Change password" for? More importantly, I would like to have different fieldworkers have different passwords to log in with their different usernames--any insight on how to implement that appreciated. Thanks!
