multiple recipients encryption and decryption in gpgsm

[Yves T]

Dears,

A client uses gpgsm with multiple recipient options. The first option refers to his own certificate, the second option to the recipients certificate.
The receiving end has trouble decrypting the file. Output mentions
gpgsm: error decrypting session key: No secret key
gpgsm: decrypting session key failed: No secret key

The solution which was mentioned to us was to use local-user option but this does not seem to work.

Is it possible in gpgsm to encrypt for different recipients and how can they decrypt. Can you please complete with an example?
Thank you.
