Cannot allocate memory error on mount

[joe hefner <joe.hefner-/E1597aS9LQAvxtiuMwx3w@public.gmane.org>]

On a recent Fedora (13), I am seeing a mount failure message that I can not explain. I have a Windows Server 2003 a with a share set up for access only for a specific username (say userfoo). If I try to mount it from Linux, using 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.
 
dmesg and /var/log/messages show an odd entry about failure to get root inode. Setting cifsFYI shows that errno 13 is being seen on the client side, but then this inode error occurs.
 
Has anyone seen this? Any ideas what is happening?
 
Thanks, Joe H.
