Case-insensitive regexps in rlm_files

In rlm_files, I can't see how to make a case-insensitive regular expression. ----------------------------------------------------------------- DEFAULT User-Name =~ "(?i:foo)" # nope, not supported by POSIX ERE. Logs: # "Invalid regular expression (?i:foo)" DEFAULT User-Name =~ /foo/i # actually matches the character sequence "/foo/i" ----------------------------------------------------------------- Am I missing a trick here? If I make a patch for this, would you prefer the first or second to be implemented? The second is nicer to use, but is probably harder to implement. The first could be done as a frig by stripping off an outer (?i: ... ) and setting the REG_ICASE flag if seen. Regards, Brian.
