InfoPath Dev

 I am attempting to identify users that open up a certain form.

I was able to use the account ID for the user and I wanted to show a value such as the permission allocated to the user (for example 'Design', 'Full control' etc) or the sharepoint group he belongs to.

I have tried with the data connection SOAP called

GetUserMembership

GetUserCollectionFromGRoup

GetgroupcollectionfromUser

Getrolesandpermissionsforcurrentuser 

getusercollectionfromsite

getusermembership

and I was not able to get anything useful, either they were giving me errors (control binding is not supported) or they were  giving me info I cannot use (such as the AD group).

Can someone tell me if there is a comprehensive list of the above functions to be able to understand what else I could try or what I am doing wrong? or someone to tell me the exact procedure to make appear the SP permission or the SP Group.

Also is someone listing how many of the above commands do not work in SPonline? 

 Adding to what I wrote before, I did manage to get something out of it with GetCommonManager. The result is that I see the userid of the manager of the person logged in in the SPO only format i:0#.f|membership|[email protected] which is fine.

My problem is that when opening the form I get an error message

An error occurred while trying to connect to a Web service.

An error occurred while trying to connect to a Web service.

.

Not sure that with this correlation error Microsoft can help, anybody know what is the reason for the error?

If I click ok and the form displays correctly. 

 ok, I was able to remove the error message by deleting some other connections I created that were not right
