Yes it is - HP encrypts the passwords in blocks of 8 characters - using the
standard Unix encryption technique (aka crypt) - But c50a will only decrypt
the first 8 characters of the password.

I'm currently evaluating 'John the Ripper' for a similar purpose - which
seems to have good and fast success rates (around 200,000 crypts/s on my
1.4G P4 Linux box)
Mangling the u_pwd file with /etc/passwd is actually very easy - I did write
a shell script to do this once; but have lost it; essentially its:
awk -F ':' {print $1} /etc/passwd |
while read user
do
typeset -L1 I=${user}
Password=$(awk -F = 'BEGIN { RS=":" } $1 == u_pwd { print $2 })
/tcb/auth/files/${i}/${user})
grep "^${user}" /etc/passwd | sed "s/\*/${Password}/"
done
