Ravi,

user_name=`echo $QUERY_STRING | awk -F"=" '{print $2}'`
Pass_word=`echo $QUERY_STRING1 | awk -F"=" '{print $2}'`

now search for user_name and password in the file as below.

ex: cat reference_file.txt

Name | Gender |Password
rohit|male|xxxx
robin|male|YYY

Code:
 
user_name="robin"
res1=`awk -F "|"  -v var_name=$user_name  '{if ($1==var_name){print "found";exit} }' reference_file.txt`

if res1 is "found" go and search the file again for password validation.

OPIESU(1)						      General Commands Manual							 OPIESU(1)

NAME
opiesu - Replacement su(1) program that uses OPIE challenges SYNOPSIS
opiesu [ -f ] [ -c ] [ user_name ] DESCRIPTION
opiesu is a replacement for the su(1) program that issues OPIE challenges and uses OPIE responses. It is downward compatible with keysu(1) from the Bellcore S/Key Version 1 distribution and the su(1) program from the 4.3BSD Net/2 distribution. OPTIONS
-f If the invoked shell is csh(1), this option prevents it from reading the ``.cshrc'' file. (The [f] option may be passed as a shell argument after the login name, so this option is redundant and obsolescent.) -c Set console mode where the user is expected to have secure access to the system. In console mode, you will be asked to input your password directly instead of having to use an OPIE calculator. If you do not have secure access to the system (i.e., you are not on the system's console), you are volunteering your password to attackers by using this mode. user_name The name of the user to become. The default is root. EXAMPLE
wintermute$ opiesu kebe otp-md5 498 wi910502 (OTP response required) kebe's password: (echo on) kebe's password: RARE GLEN HUGH BOYD NECK MOLL wintermute# FILES
