Example: Create users and roles from two text files

There are various approaches for populating ArcGIS Server's built-in security store using the ArcGIS REST API. This particular script creates users and roles using two text files: one containing a list of users and the other containing a list of roles. With this script it's possible to assign a single user to multiple roles.

The input file containing the roles should be structured like this:

#Role|Description|Privilege
admins|Server Administrators|ADMINISTER
publishers|Service Publishers|PUBLISH
rangers|Park rangers|ACCESS
volunteers|Volunteer staff|ACCESS
visitors|Visitors|ACCESS

Role—A name for the role.
Description—A user-friendly description for the role.
Privilege—The ArcGIS Server role type that determines the level of privilege held by the role. There are three levels of privilege: ADMINISTER|PUBLISH|ACCESS. See Restricting access to ArcGIS Server to learn about these.

The input file containing the users should be structured like this:

#User|Password|EMail|FullName|Description|RolesThatTheUserBelongsTo
John|changeme|johndoe@esri.com|John Doe|Server admin|admins
Jane|changeme|janedoe@esri.com|Jane Doe|Server publisher|publishers,rangers
Amy|changeme|amy@esri.com|Amy Doe|Summer intern|volunteers
Bob|changeme|bob@esri.com|Bob Doe|Park visitor|visitors

User—The name for the user
Password—The password for the user
EMail—The e-mail address for the user
FullName—The full name or detailed name of the user
Description—A description of the user
RolesThatTheUserBelongsTo—A comma-delimited list of roles to which the user should be assigned

You can modify the script code to expect a different property set or set some of the above properties by default.

Below is the script body:
