users gets Error 401 trying to deploy gacAssembly in remote server

Hello !!

I'm trying to allow some dev users (non-administrative) to directly deploy some dlls to the production server's GAC:
msdeploy -verb:sync -source:gacAssembly=TheDLL -dest:gacAssembly,computerName=TheServer,username=Dev01,password=Dev01pass

These users are already registered in IIS Manager Permissions, the Management Service is up and allows remote connections, and the dll is in their own GAC. The users also can remotely connect with IIS Manager. I really don't know what's going wrong.

 Does anybody knows if its really prossible or if I'm doing something wrong ?

 Thanks a lot !
