[Samba] Client connection limit!?

[Thomas Riedrich]

Hello,
I didn't find any information on the net: Is there any client connection 
limit in Samba? We have about 70 clients accessing one Samba PDC, and 
sometimes we get errors from client machines that can't connect and they 
say that the "maximum connections" on the server has been reached. I 
din't find any such thing in the smb.conf - except one paramater where 
you can manually set a limit, but we didn't set this limit.
