thanks for your answers,

maybe I need to specify a bit more....

mainly I'd be interested in what the error in the smbd.log means, and 
how I could get a trace what exactly the netapp or the windows client 
sent to authenticate.

Actually, since last friday all my tests are running in a virtual 
replica of the real system using the netapp ontap simulator and a copy 
of my univention ucs appliance vm.

the user "cliff" is a test user (Clifford Unger from Death Stranding ...)
so there should not be a sensible data leak when extracting logs or 
anything. I guess..

thanks again!
