It is possible to restrict write access to the FATMEN catalogue using an ACL file. The ACL file consists of 3 fields.
FATMEN.ACL. This file
resides in the directory or on the mini-disk containing the
catalogue for which the update is being attempted. Thus, in the
case of the CDF experiment, the file will be in the directory
pointed to by the symbol or variable FMCDF.
Lines beginning with an exclamation mark, an asterix, a hash or slash asterix treated as comments.
Example of an ACL file
/* FATMEN.ACL file for CDF experiment at Fermilab */ ! ! ! ! ! ! CDF FATMEN Superusers: can modify any directory ! ! ! LINGFENG * //FNAL/CDF ! ! ! ! ! ! CDF FATMEN Test users: can modify the subtree //FNAL/CDF/FATMEN ! ! ! CDF_FATM * //FNAL/CDF/FATMEN ! ! ! ! ! ! CDF FATMEN General users: can modify <user> tree. ! ! ! e.g. FRODO can modify //FNAL/CDF/USERS/FRODO ! ! ! <user> * //FNAL/CDF/USERS/<user> ! ! ! ! ! !
