Hello, I¹m not sure if this is the right list to ask this question. I¹m trying to create a filevaulted user, who can log in with the pubkeyhash method in the AuthenticationAuthority field. As far as I know tokenadmin create-fv-user is broken and hasn¹t been fixed yet. So I¹ve been trying to create a sparsebundle using: hdiutil create -size 20m -encryption -fs HFS+J -pubkey 6225DF186D119D08DA6850C74C948A182F5DE7C2 enc.sparsebundle hdiutil: create failed - error 0x80010914 I keep getting this error. When I use a different hash, I don¹t get an error at all, but instead it returns the usage: Usage: hdiutil create <sizespec> [options] <imagepath> hdiutil create help When I export the certificate and use that instead of the public key hash value I get the same error value. Does hdiutil do some sort of test on the hexidecimal pubkeyhash values? Is this method even possible? I figured that I could create the sparsebundle then just drop it into place by modifying the NFSHomeDirectory field.
