We’are trying to set up LDAP add on for their use and an error is produced testing LDAP matching rules.
We’ve achieved a LDAP configuration that connects fine and retrieves correcttly the list of Ms-AD attributes , like next image shows:
We didn’t create yet any LDAP matching rule but we wanted to test the retrieval of information from Ms-AD through the “Test rules” button. But, when it’s pressed, next error appears:

How can we know which item is null and it’s causing the problem? Any idea?
Hi,
For better resolution of the problem, here it is the app.log file corresponding to the error:

I’d very grateful if someone could help to solve the problem.
Could you please clarify if the corresponding user exists in CUBA at the moment you are trying to test the matching rules? If yes, which roles does it have?
Also, which CUBA and LDAP add-on versions do you use?
Hi, Gleb.
Thanks for your answer that helped me to find the problem.
When I reported the error there wasn’t any matching rule created, because I’d only want to test the right access to Ms-AD attributes for this user.
Now, I’ve just created one matching rule, the user has the appropiate application rol assigned and the test rules process obtains the correct application rol, as you can see:
Perhaps the only bug to solve is catching the use case that pretends testing the rules when there isn’t any rule created.
