Force primary email address from admin side

Hi,
is there a way to change the primary email address for a user through the Indico shell?

Thank you in advance.

Best regards,
C. Urban.

I guess it should be something similar to this: [SOLVED] Login issues, no such user - #2 by ThiefMaster

Anyway, I solved with new account registration and merging the old one with the new.

Cheers,
Cristiano.
