saplogon pad 740 - making connection entries read only

Hi,

Does anyone know how to set the saplogon pad globally so that users cannot amend the connection entries ?

we have installed the sapgui 740 on citrix set the whole thing to read only as per the admin guide with registry key

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SAP\General]

"AllOptionsReadOnly" (REG_DWORD) = 1   

"CurRegValReadOnlyActive" (REG_DWORD) = 0

but this still allows users to amend and delete connection entries

the admin guide mentions the following registry key

[HKEY_CURRENT_USER\Software\SAP\SAPLogon\Options]

“NoEditFunctionality” (REG_DWORD) [Default: ”0”] {0 = inactive; 1 = active}

but this only disables it for the current user not globally for all users which is what we need in a citrix environment

Thanks
