i keep having "ERROR: Malformed request url (HTTP 400)" when doing 'cinder list'. I dont understand why. It kinda seems related to endpoints according to some googling. I have them configured as in the doc (and it worked well for all other services)

playing with 'cinder --debug list' i can see the failing request is
	curl -i http://verdi:8776/v1/f86fd98e4388460b8914e23de11546fa/volumes/detail -X GET (... + token.)

which seems perfectly ok to me.
there's nothing in cinder logs on the controller
f86.. is indeed the tenant id
