Changing multiple keychain items to the same password

Question

I work in a corporate environment that uses a Windows server with Active Directory to manage the company network.  Macs are integrated to the network, but Open Directory is not being used.
The login for the Macs is the same as the network name and password.  Whenever your password is changed on the network, you must update your login keychain to use that password too.  The problem comes with other applications, such as Entourage, that use the same network password but store it in a separate keychain item.  When the login keychain is updated to the new network password, the keychains for these applications are not and must be manually changed.
Is there any way to synchronize login passwords to keychain items?  Is there a script capable of changing multiple keychains to the same password automatically?  Is there third party software that is able to accomplish either task?  A solution not mentioned?
Our company is currently using Snow Leopard but plans to migrate to Lion soon, so solutions for any platform are welcome. 
Thanks to anyone that is able to provide information. 
Regards,

Hi Nishanth,
1) how to pass value one by one
in select options..we will be filtering the values in some table..example if s_ebeln is our select-options...then we will be doing a select..like...............
select fields from vbak into int_vbak  where ebeln in s_ebeln
so if in the table int_vbak if field ebeln is there ..we will know which all ebeln is there..............
i.e,if range is 1 to 100 for s_ebeln and 1,2,99 are the only 3 ebeln present in table vbak as of now ...................
then in select query , we fetch ebeln into int_vbak as an additional field( if it is not a "select *")  we will get all the 3 ebeln 1,2,99 into int_vbak.....so we can pass these fields one by one by looping at int_vbak and appending it to fresh internal table..........
declare an internal table with ebeln as the field..loop and do the append
*****putting values of ebeln into a new internal table
loop at int_vbak.
wa_ebeln = int_vbak-ebeln.
append wa_ebeln to int_ebeln.
endloop.
*******delete duplicate entries
sort int_ebeln.
delete adjacent duplicates from int_ebeln.
2) how to append and join the data in the v_postab
First..... declare another table same as v_postab say,v_postabfinal as example...........
after each "call function"...in the loop ...do the following...
loop ....
refresh v_postab[].  "clear before each fxn call
call function XXXX.
if v_postab[] is not initial.
append lines of v_postab to int_postabfinal.
endif.
endloop........
what this append statement does is that every time the internal table has some values..it adds these lines to v_postabfinal without deleting the old entries...so you will have all the values with respect to each value of select-options passed..
Hope i have made the idea clear with these examples
Pls check and revert
