If you're trying to upload a file from filemaker pro (using the sharing submenu) to filemaker server, it's the server admin console user/password that you need to use, NOT the file's username and password.
The file's usernames and passwords are used to open the file once it's already hosted, or locally when the file isn't hosted. But those accounts live inside the file, and have nothing to do with the filemaker server admin console.
FMS has only one account to access the console. When you install FMS, you may chose this account name and its password.
To upload a database to the server, you do this from FMP or FMPA. Pick this menu choice : File > Sharing > Upload to FileMaker server... You have to do this from the file you wish to upload to the server. First the file is closed and then a list of local servers or remote servers is displayed. You need to pick the server and enter the admin/password for the Admin Console.
To get the server documentation, go to Get A FileMaker Download or Database Update | FileMaker the scoll down to the bottom and click on Product Documentation.Click on" Recent products - Get manuals, user guides and other reference material" and there you will find documentation for FMS 14. For older products, there is a link at the bottom.
Hope that helps
User Accounts are handled at the .fmp12 file level
It seems there is no account administration in the file maker admin-console.
What are you trying to achieve:
1- give people access to a hosted file?
2- give people access to the FMS admin console?
#1 is handled as coherentkris stated: in the security settings of the FM file itself.
#2 has a couple of different options:
- you can use external authentication to give a group full access to the admin console, then all you need to do is add the right people to the external group. To set it up on the FMS side, in the admin console > General Settings > admin console tab > External Group
- if you don't want people to have full admin rights to the console you can use the sub-admin feature: in the admin console > General Settings > Administrator Groups tab
