samba - Nov 2004 - long connection time when mapping shares - ADS member

Hi,

We have got a samba 3.0.4 server as an ADS member server running solaris
8 on a sun sparc.

When users try to map a samba share it takes 5-12 seconds until the
share is mapped. 
And if a user tries to enter a mapped share after some time, that user
is again forced to wait until he is allowed to connect to that share.

I'd like to know if this is a normal behaviour and if there is a way to
improve connection speed.

Apparently it's not the fault of the Domain Controllers as connections
to servers that are ADS members but not samba servers is much faster.


Here is a part of the smb.conf:
