The AuthDBMGroupFile directive sets the name of a DBM file containing the list of user groups for user authentication. Filename is the absolute path to the group file.

The group file is keyed on the username. The value for a user is a comma-separated list of the groups to which the users belongs. There must be no whitespace within the value, and it must never contain any colons.
