Hello

I'd like to use the slapo-dynlist overlay, to generate an automatically updated list of attributes onan object. My problem is that I want the attribute name to be different than the original:

I have

dn: cn=list,o=home objectClass: groupOfURLs cn: list memberURL: ldap:///o=home?foo?sub?(objectClass=fooClass)

In slapd.conf: overlay dynlist dynlist-attrset groupOfURLs memberURL

A search on cn=list,o=home gives me: dn: cn=list,o=home objectClass: groupOfURLs cn: list foo: value1 foo: value2 foo; value3 ...

But I would like it to be displayed that way: dn: cn=list,o=home objectClass: groupOfURLs cn: list bar: value1 bar: value2 bar; value3 ...

It seems this is not possible with current software (please correct me if I'm wrong).

You can already do this, if I understand what you are trying to do:

dynlist-attrset groupOfURLs memberURL foo

and miss out foo from:

memberURL: ldap:///o=home??sub?(objectClass=fooClass)

See the man page:

"In this case, the <attrs> portion of the URI must be absent,and the DNs of all the entries resulting from the expansion of the URI are listed as values of this attribute."

Is that what you are after?

It seems this is not possible with current software (please correct me if I'm wrong). I propose a contribution to slapo-dynlist, to include attribute name remapping capability. In the config file, this qould be configured by extending the member-ad parameter:

overlay dynlist dynlist-attrset groupOfURLs memberURL foo:bar

Of course, for backward compatibility, dynlist-attrset groupOfURLs memberURL foo would still be equivalent to dynlist-attrset groupOfURLs memberURL foo:dn

The modification you propose could make sense, but I believe it could be more general if more than one attribute could be mapped. The behavior in case an optional arg#3 is added to the dynlist-attrset statement should be viewed as something different: it is basically intended to make slapo-dynlist implement dynamic groups, that's why it expands to the dn. To obtain what you mean, the syntax should rather be something like

dynlist-attrset groupOfURLs memberURL [foo:]bar [...]

where if [foo:] is absent, [dn:] is used instead. Any further attribute pair, if present, would be mapped as well.

I suggest you file an ITS for this proposed enhancement.
