TFS official edition User restrictions

Today, I talked to Jonson, a netizen, about the user logon problem during TFs usage. I found that the trial version of TFS is different from the official version.
Our network environments are working groups and TFs are deployed on a single server.

Q: Do I have to create a local user on the client computer after a team member creates a local user on the TFS server?
A: No. I tried it. I used to log on to TFs with different users in my notebook from Team explorer. These users have been created on the TFS server beforehand and are not created locally on the client (my notebook.

Materials from Microsoft:
Both the team Foundation client and team Foundation server are in the workgroup.
All users who need to access the team Foundation server must create a local user account on the server. The local user account must be added to the team Foundation server-level and project-level groups so that the user can be authorized on the team Foundation server. When connecting from a team Foundation client (such as the team resource manager) in a workgroup, the client user account creden, must match the user account creden, on the server, otherwise, the team Foundation server prompts the user to enter the user name and password of the account.

Q: after creating a user on the TFS server and configuring permissions according to my instructions in "team Foundation Server user management (Working Group)", he still cannot log on to TFs from Team explorer, the message "tf50637: Only Windows users can be added to the license group. ", Why? Why haven't I met?
A: I use a trial version. There is no built-in group "Team Foundation licensed users". Jonson uses the official version. It seems that this group only appears in the official version, the user must be added to this group (role. In addition, the trial version does not have a limit on the number of users.

The red coil does not exist in the trial version.

ADD team members to the team Foundation licensed users group.

Q: When you log on to TFs from Team explorer on the client machine, a logon form asking you to enter the user name and password is displayed every time. However, on the TFS server, only the user name and password are required for the first time, after that, remember that the login page is no longer displayed, and there is no chance to change the login user. What should I do?
A: I don't know. I have encountered this problem. It cannot be solved.
