the 'import proposal' option for the LDAPMAP transaction is disabled

Hi

I am trying to set LDAP authentication for my SAPGUI users - so they can login with their Active Directory logon/password

At the Mapping stage I am trying to import a proposal - but the Utilities --> Import proposal  option is greyed out

In fact everything is disabled but the 'Export XML'

Any idea what is missing ?

I am SAP_ALL profile - so I don't think its authorization

We have NetWeaver 7.0  SP 16   ( 7.2 Kernel )

thanks
