Problem:
When user surf to the PAW, they are not administrator and can not add other users.
Surf to http://pawservername.domain.com
Click on the user — and see there is not a option for Administration.
This is a new PAW setup with CAM authentications.

Solution:
The first users that you add in a TM1 instance as ADMIN will be admin in paw when you login to paw. Therefor you must add CAM users to a native TM1 instance first.

Open up a Tm1 application in Native mode. Like Proven_Techniques.
Open C:\Program Files\ibm\cognos\tm1_64\samples\tm1\Proven_Techniques\tm1s.cfg in notepad++.
Add the lines;
IntegratedSecurityMode=2
ServerCAMURI=http://caservername.domain.com:9300/p2pd/servlet/dispatch
ClientCAMURI=http://caservername.domain.com:80/ibmcognos/bi/v1/disp
Close TM1 architect.
Update the C:\Users\%username%\AppData\Roaming\Applix\tm1\tm1p.ini file with
AllowImportCAMClients = T
CognosGatewayURI = http://caservername.domain.com:80/ibmcognos/bi/v1/disp

Start PAW administration console and surf to http://pawservername.domain.com:8888
Setup like this (change to your servers name);
TM1 Admin Server URI: https://paservername.domain.com:5898
TM1 Application Server Gateway URI: http://paservername.domain.com:9510
Authentication Mode: TM1
TM1 Login Server URI: https://paservername.domain.com:5011
Click validate and update.

(This TM1 instance you point out with the HTTPport number is the instance that will define the first ADMIN in paw, even if you use security mode 5).

Start TM1 Architect and login to Proven_Techniques as Admin.
Go to Security – Client/Groups. From menu Clients select Add New Client.
Add your CAM user from your AD domain, that you want to be ADMIN in paw.
Mark the user to be ADMIN in TM1 Architect. Click OK.
Exit Tm1 Architect.

Open C:\Program Files\ibm\cognos\tm1_64\samples\tm1\Proven_Techniques\tm1s.cfg in notepad++.
Change; IntegratedSecurityMode=5
Save the file and restart the TM1 instance.
Now TM1 instance is using CAM authentication.

Update PAW admin console by surf to http://pawservername.domain.com:8888
TM1 Admin Server URI: https://paservername.domain.com:5898
TM1 Application Server Gateway URI: http://paservername.domain.com:9510
Change to Authentication Mode: CAM
Set IBM Cognos BI Gateway URI: http://caservername.domain.com:80/ibmcognos
Set IBM Cognos BI Dispatcher URI: http://caservername.domain.com:9300/p2pd/servlet/dispatch
Set IBM Cognos BI Authentication Namespace ID: AD
Click Validate and update.
Click on status tab – wait until CPU usage is below 1%.

Surf to http://pawservername.domain.com
Login as the CAM user you have given ADMIN rights in Proven_Techniques.
This user should now have a ADMINISTRATOR option under its name.

The list will only show name for people who have already try to login.
