Double escaping \ in regex in slapo-constraint directives in slapd.conf

[Tim Watts <tw@dionic.net>]

Could someone make sure I'm not going mad before I call this a bug?

In slapd.conf:

constraint_attribute mail regex ^[^@]+@[a-z0-9\-]+(\.[a-z0-9\-]+)*$


stick this into ldapmodify and it is allowed:

replace: mail
mail: mrwibble-bble@example#com


This looks like the last \. is being parsed to . before the regex engine 
sees it.


With this regex:

constraint_attribute mail regex ^[^@]+@[a-z0-9\-]+(\\.[a-z0-9\-]+)*$

the constraint acts on mrwibble-bble@example#com
but allows
mrwibble-bble@example.com

which is correct.

Is this a bug in the code, a bug in man -S5 slapo-constraint
(which does not mention double escaping is necessary) or am I insane?

Makes me wonder what is happening with the \-

Hmm

Both:

constraint_attribute mail regex ^[^@]+@[a-z0-9\-]+(\\.[a-z0-9\-]+)*$
and
constraint_attribute mail regex ^[^@]+@[a-z0-9\-]+(\\.[a-z0-9\\-]+)*$

accept mrwibble-bble@example.c-o-m




I'll investigate further is someone would kindly rule out anything I may 
have overlooked.


Cheers,

Tim
