I have a Windows Server 2003ýa with a share set up for access only for a specific username (say userfoo). If I try to mount it from Linux,ýusing userfoo and the correct password all is well. If I try with a bad password or with some other username (userbar), it fails with "Permission denied" as expected. If I try to mount as username = administrator, and give the correct administrator password, I would also expect "Permission denied", but I see "Cannot allocate memory" instead. > ý > dmesg and /var/log/messages show an oddýentry about failure to get root inode. Setting cifsFYI shows that errno 13 is being seen on the client side, but then thisýinode error occurs. > ý > Has anyone seen this?

Fix this by propagating the actual error code back.
