There seems to be a reproducible bug in the ECMA 2.2 for trying to add Password Management after creating the MA without one. The Password Management settings on the "Configure Extensions" screen do not show even after "Refresh Interface".
Sync Engine Build v4.1.3599.0
I created an ECMA 2.2 without support for Password Management. I put the Capabilities "SupportPassword" as false, and did not include the IMAExtensible2Password Interface. During the creation of the ECMA, I noticed the "Configure Extensions" screen does not include any information about Password Management.
Now I would like to implement password sync in this ECMA, so I added the capabilities "SupportPassword" = true, and added in the IMAEXtensible2Password Interface with the proper code. When refreshing the interface in Sync Engine it shows that the MA supports Password Management, but the dialog screens never appear. The only way for them to show is for me to delete and re-create the management agent (not even a Export/Import/Update will work)
