If one directory entry (object) contains a multivalued attribute
and if the value is allowed to contain a comma:
foo = there, not here
foo = over there
the query ldap:///<base>?foo?sub?<filter>
formerly returned the string
there, not here, over there
That's ambigous.
Current versions return the string
there,, not here,over there
That's clearly a list, using ',' as the separator.
If the lists values contain the separator, it has to be doubled.
E.g.
hostslist relay_from_hosts = 127.0.0.1 : ::::1
or
hostlist relay_from_hosts = <; 127.0.0.1 ; ::1
The last host list changes the list separator with the '<…' syntax.
I think, for your purpose, changing ,, to , would suffice. But the
perfect way would be using "reduce" to concat the values of a
multivalued attribute
text = ${reduce{<, ${lookup ldap{…}}}{}{$value$item}}
