Hi Simon,

The storm is over and users no longer complain.

It seems that all the problems came from a disorder in the NAS 
permissions. I didn't mention that the home is hosted by a NAS.

I guess this disorder disturbed first the sssd and mkhomedir and since 
guix.

I will be careful for the next user.

Thank you again  for your efforts and advices.

Regards,
