I have copied a db to the fmserver library and all seems normal except when I try to assign read write privileges to the fmsadmin group, it does not appear as an option. Consequently, if I open the db from a client the error message "the action cannot be performed because the file is not modifiable" constantly appears.
If I try to create the user group fmsadmin the message "the name is already in use" is displayed, so it appears the group exists, it just does not appear in the drop down list to add to the file privileges.
FMS ver 15, Mac OS El Capitan 10.11.5
Any ideas anyone?
