Hi,

I would like to create a rewrite rule with slapo-rwm using back-relay to concatenate two different attributes in an other one? Something like this with an approximate syntax:

map attribute cn concat(givenName sn)

or with Perl syntax:

map attribute cn "$givenName $sn"

Is it possible to do this with rewriteRules directives?

No (at least, not in a straightforward and reliable manner). You'll need to write some code. I'd note, however, that things like that are far beyond the spirit of LDAP; it is a container, not a generator of fancy strings. Store the values you need, retrieve them as static values.

p.
