Hope you have already run the kUpdatehtml.sh after updating the server.conf file. Can you please provide me the scren shot of the error message and user creation window. Because I think there is nothing else to be done..
From what I understand, PPM will support LDAP and PPM authentication modes individually but not at the sametime. If you are trying to apply both the authenticaiton modes simultaneously then I believe it will not work.
Just a clarification of the Bhanu's comment, you can have both authentications modes activated by updating the parameter to have ITG, LDAP. What is not possible is to have both authentications modes for one user at the same time. you need to go to the Sys Admin tab-> Users -> Authentication Mode and set it (you can only select one mode per user)
But still you can have some users authenticating trough LDAP, and other users authenticating trough ITG
By any chance are you also using single-sign-on? If you are, and are normally accessing ppm using another url like ppm.mycompany.com and are now trying to go direct to myserver:8080 then it won't work...PPM will throw you that same message.
Yes it possible to have two different users use two differnt modes of authentication and login to PPM, but you cannot do this while also enabling SSO.
If you're NOT using SSO, that means the URL for PPM takes you to PPM's login page. The user enters their username & password and PPM authenticates it according to whatever order is set in server.conf, for example PPM,LDAP means it will always look for a password set in the workbench first, and failing that will try to auth against whatever LDAP server you have configured.
Note that this is completely different from SSO. SSO means that you have some external system validating the users and forwarding the traffing to PPM. The users never see the PPM login page. You use a URL like ppm.mycompany.com and if you try to connect direct to the PPM server with the servername:8080 it will always reject this.
