Create service user accounts for the commit and edge server

To support secure communication between the commit server and the edge server, a user account of type service must be created. Although you can use a generic service user name for multiple edge servers, in this example we use a unique service user name for the one edge server.

Create a service user account for the commit server:

First, issue the command:
```
$ p4 user -f svc_chicago_commit
```
Then, in the user spec, insert a line that sets the user Type: field to service:

User: svc_chicago_commit
Type: service

Save and close the user spec.
Create service user account for the edge server:

First, issue the command:
```
$ p4 user -f svc_tokyo_edge
```
Then, in the user spec, insert a line that sets the user Type: field to service:

User: svc_tokyo_edge
Type: service

Save and close the user spec.
To prevent the service user logins from timing out, add the service users to a group with an unlimited timeout:

First, issue the command:
```
$ p4 group no_timeout
```
Then, in the group spec, set the Timeout: field to unlimited

Add a line under Users: field for svc_chicago_commit

followed by another line for svc_tokyo_edge

So that the group spec contains the following:
```
Group:	no_timeout
...
Timeout:	unlimited
...
Users:
svc_chicago_commit
svc_tokyo_edge
```
where ... replaces lines of the spec that do not require changes.

Save and close the group spec.
Assign passwords to the service user accounts by providing a value at the prompts.
```
$ p4 passwd svc_chicago_commit
$ p4 passwd svc_tokyo_edge
```
In the protect spec, assign super protections to the svc_chicago_commit and svc_tokyo_edge service users.
```
$ p4 protect
super user svc_chicago_commit * //...
super user svc_tokyo_edge * //...
```
