Hi,
when i mount a cryptovolume, i don’t have problem, but i don’t see file.
The destination directory before mount, is 777, but after is “d???” and isn’t readable because i see access deny.
Any ideas?
One place you can check are the ‘Vault Options’ before you unlock. There, you find a tab called ‘Mounting’ and I would check if there are any ‘Custom Mount Flags’ set (especially umasks). There is also a ‘Read Only’ checkbox that could cause the inability to read the mounted vault.
This is my option
-oauto_unmount -ouid=1000 -ogid=1000 -oumask=0111
but i don’t access to the directory after mount 
I use this crypt share from suse, windows, etc but with kubuntu i have problem
