Does anyone have any experiance of these problems
OS Redhat 6.2
Samba version 2.0.7
Machine runs a slave NIS server and has 2 sets of groups one for staff and
one for students e.g.
staff0:x:staffuser1,staffuser6,staffuser11,staffuser16,staffuser21,staffuse
r26......etc
staff1:x:staffuser2,staffuser7,staffuser12,staffuser17,staffuser22,staffuse
r27......etc
staff2:x:staffuser3,staffuser8,staffuser13,staffuser18,staffuser23,staffuse
r28......etc
staff3:x:staffuser4,staffuser9,staffuser14,staffuser19,staffuser24,staffuse
r29......etc
staff4:x:staffuser5,staffuser10,staffuser15,staffuser20,staffuser25,staffus
er30......etc
Student groups follow the same format but are groups stud0 to stud9
all the groups for each user are correctly reported by linux and I can find
no other problems and logon speed under linux is fine. The problem we have
is that we have upto 550 pc's mapping to a share which runs off this box
(Details of share below). All the main logons happen within a short period
of time i.e. when the students login in a morning and after breaks, for
some reason it is taking a long time for any windows NT machine to map a
drive to this particular share.
Samba is doing Domain Authentication and after doing various amounts of
testing and debuging I can find no way of improving the speed of the drive
mapping process. We are thus experiancing 2 problems, firstly a lot of the
drive mappings will fail (with a 240 error) when lots of people are logging
on and secondly the box is put under so much load due to the exessive
amounts of time samba spends checking against the groups. If I copy the
password, shadow and group files off the primary nis server and put them on
the local machine the drive mappings are almost immediate. We presently
have 1000 or so students in the groups and this will double if not tripple
by the end of the year, There are also around 300 staff accounts.
This share is a specific one which allows students Read only access and
staff read/write access. the files in the share are owned by the user/group
shares/shares respectivly.
Any help or ideas would be greatly appreciated

Lee,
We use Samba 2.07 and Solaris 7, but essentially to do what you do.
I notice that you are explicitly telling Samba to use NIS groups, we use
NIS but I use a stright compile of Samba and list the groups just as
groups. (no plus sign)
I let the Unix (Linux) resolving routines do the lookups outside of the
Samba software.
We have a similiar setup to yours here and experience no delays with
mass logon's.
We have around a housand PC's hanging off one server and we have very
few problems.
Anyway I would suggest to try and remove the plus signs and see if it
speeds things up,
the other thing is are you doing a build of Samba with NIS enabled?
Are the usual thing's OK with the system? Memory etc..... I allow around
4 Mb per Samba
session. Have you checked the system with all the available tools while
this is happening?
Scott.
