Re: authz-regexp and uid's

You are right, I did misinterpret authz-regexp to be a more general query rewriter.  I had actually come to this conclusion about an hour after sending this email.  Sorry for the wasted time.  I'm taking a look at the rwm overlay now.

Thank you for your time.

It seems you heavily missunderstood the purpose of authz-regexp. It is
only meant for converting user names as used during SASL authentication
to LDAP DNs e.g. for Authorization purposes. E.g. if you authenticate
against you slapd as joe@YOUR.KRB.REALM using SASL/GSSAPI you can use
authz-regexp to map that name to an LDAP DN that makes sense in your

For details see: http://www.openldap.org/doc/admin24/sasl.html

authz-regexp is NOT
- able to rewrite DNs in LDAP Simple Bind Request.
- a general purpose tool to rewrite LDAP Search Results.

If you can't fix you application to be more flexible in regards to how
your DNs must look, it might be possible to achieve what you want through
the rwm-Overlay, but I don't know the overlay well enough to say for
sure. See the slapo-rwm man-page for details.
