best pracitces to add wifi network to user’s login.keychain?

I am thinking about deploying a launch agent that runs as the user logs in, as the user to add our wifi network to the keychain. Thoughts? [code] #!/bin/bash # set user's login.keychain to have our wifi passsword # run this as the user, via user agent /usr/bin/security find-generic-password -a usd500_wpa case `/bin/echo $?` in 0 )) hasloginkeychain=yes;; * )) hasloginkeychain=no;; esac if [[ $hasloginkeychain -eq yes ]] then /usr/bin/security add-generic-password -a usd500_wpa -s AirPort -D "AirPort network password" -l usd500_wpa -w mypasskey -T /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -T /usr/libexec/airportd -U ~/Library/Keychains/login.keychain else /usr/bin/security add-generic-password -a usd500_wpa -s AirPort -D "AirPort network password" -l usd500_wpa -w mypasskey -T /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -T /usr/libexec/airportd -A ~/Library/Keychains/login.keychain fi exit 0 [/code] Thoughts, suggestions, pointers, better methods all welcome. Thanks in advance! Tom
