I think that's misleading. The error in the book involved a user
matching multiple lines for a single location, like the user 'test'
above. When that happens the user gets the union of all the
permissions, the book mistakenly claimed the first matching line was
used.

Using the rules above in a file z.z:

$ tools/server-side/svnauthz-validate z.z rcrespo /ABC
user 'rcrespo' has rw access to '/ABC'
$ tools/server-side/svnauthz-validate z.z rcrespo /DEF
user 'rcrespo' has no access to '/DEF'
$ tools/server-side/svnauthz-validate z.z test /DEF
user 'test' has rw access to '/DEF'

It appears the authz file is correct and denies rcrespo access to /DEF.

I suspect the problem is a failure to enable authz at all--editing the
wrong config file, accessing the wrong repository, failed to restart
apache, something like that.
