删除整个密码策略:
<dict>
<key>PayloadDescription</key>
<string>Configures security-related items.</string>
<key>PayloadDisplayName</key>
<string>Passcode Policy</string>
<key>PayloadIdentifier</key>
<string>uk.ac.cardiff.insrv.eduroam.iphone3.7.passcodepolicy</string>
<key>PayloadOrganization</key>
<string>Cardiff University</string>
<key>PayloadType</key>
<string>com.apple.mobiledevice.passwordpolicy</string>
<key>PayloadUUID</key>
<string>215E70FE-858E-48A8-9F34-7BD7BEE495C4</string>
<key>PayloadVersion</key>
<integer>1</integer>
<key>allowSimple</key>
<true/>
<key>forcePIN</key>
<true/>
<key>maxGracePeriod</key>
<integer>5</integer>
<key>maxInactivity</key>
<integer>5</integer>
<key>minLength</key>
<integer>4</integer>
<key>pinHistory</key>
<integer>0</integer>
</dict>
看起来这可能不起作用,因为所有的SSH密钥和文件中的哈希码看起来像是在第419-420行,我们有这些行
<key>forcePIN</key>
<true/>
改变第420行<false/>
当然值得一试。:d
