# Group Requirements

TIBCO MFT Platform Server uses three groups to perform different functions. By default, these groups are named as `cfadmin`, `cftransfer`, and `cfbrowse`.

See the following table for what each group is responsible for:

Group Name | Responsibility
--- | ---
`cfadmin` | A member of the `cfadmin` group can configure nodes, local profiles, responder profiles, as well as view audit records from all users.
`cfbrowse` | A member of the `cfbrowse` group can view audit records from all users. Note: Users not in the `cfbrowse` group can only view transactions that they perform.
`cftransfer` | A member of the `cftransfer` group can perform platform to platform file transfers initiated from Command Center. Note: If the group does not exist when a transfer request comes from Command Center, the request is processed based on the node configurations for Command Center. However, when the group does exist, but the user who initiates a file transfer from Command Center is not a member of the group, the transfer fails.

See the following table for the group requirements for both installation methods.

Note: Y means that the group must exist before the installation; N means that the group is not required to exist before the installation.

Installation Method | `cfadmin` | `cfbrowse` | `cftransfer`
--- | --- | --- | ---
Root Installation | Y | N | N
Non-Root Installation | Y | N | N

- For the root installation:
  - The `cfadmin` group must exist in the system before the installation, so the folders and files can be assigned properly to the group. It can either be a group that already exists or a new group (the group does not have to have any members in it).
  - The `cfbrowse` and `cftransfer` groups do not have to exist before the installation. You can create these groups during installation.

- For the non-root installation:
  - The `cfadmin` group must be created before the installation. You can create the `cfbrowse` and `cftransfer` groups after installation. The user running the installation has the ownership of all the installed folders and files.

Note: The installation allows you to define group names that are different from the default group names. If you define different group names, the group names should not contain an embedded space. The group name defined as the `cfadmin` group must exist before the installation. After the installation, if you want to change any group name, you can modify the config.txt file located in the $CFROOT/config directory.
