Pydio - How we login as admin to made some conf changes ?

Hi there, me again,

New question: How we login as admin in the Pydio Filemanager system ?
If password is generated during install, I probably lost it and in this case, where it is stored (to manually change it, or anything).

Thanks.

Oh ok, I'll wait "a fix" for that functionnality so
(This is the only way I found to set personnal settings like Language).
