More than one user name can be on the same line as long as there is a space separating all user names. If the same group appears on more than one line, all user names on all lines containing the group will be considered a part of the group.

AuthGroupFile GroupFile
Each group file entry must be within a directory section. If more than one group file is specified in the same directory section, the last entry will be used for that directory.
When processing requires involving groups, only one group file will be used. The one used will be the one that is nearest (and farthest from the root) to the directory for which access is being evaluated.
