Ah. The docs for "def" say "This condition is true if the named expansion
variable does not contain the empty string". You might want to clarify
that. I'll give eq a try.
I finally got it to work with this construct:
condition = "${if and {\
{match {$local_part}{^\\\\d+\\$}}\
{!eq {${lookup ldapauth {$local_part:control} {$value}}}{}}\
} {1} {0}}"
I think that besides the def problem, the extra escaping of the
backslashes and dollar sign in the regex were giving me problems.
Thanks.
