Libsmbclient - listing workgroups timeout

[Henrik Zagerholm]

Hello Derrell,

Thanks again for your thorough answers. =)

I tried setting max_lmb_count=1 on a little special network and  
instead of returning about 5 MBs it returned 0. To the defense I can  
say that this network is really weird...

After some testing it seems that the total timeout is not  
max_lmb_count*timeout. Putting timeout=1000 and the max_lmb_count=2  
still took about 15 secs to complete instead of about 2 secs.

I'll go with your suggestions (sort of) and putting standard  
max_lmb_count=2 and maybe a timeout of about 5000 even though I can't  
confirm that the timeout has any impact at all. :)

Let me know if you have any other suggestions.

Cheers,
Henrik
