It is not possible to use long netbios or workgroup names (> 15)
in Samba3 In the network neighborhood you see then the domain stripped down to
15 characters and the log.nmbd file shows this error:
ERROR: string overflow by 1 (17 - 16) in safe_strcpy
Even worse is the situation, when you have long netbios names for the machine
running Samba, then Samba does not even show up in the network neighborhood and
is not searchable by name.
I've tested this with different protocol level all from core and NT1 only, same
result. The config options below are an example of a long netbios name and a
long workgroup name which definitley not works.
##### Config #####
display charset = UTF-8
workgroup = COMPANYTEST.INTRA
netbios name = COMPANYTEST-HAUPTSERVER-SUED
smb passwd file = /etc/samba/private/passdb.tdb
passdb backend = tdbsam
min protocol = NT1
time server = Yes
os level = 64
preferred master = Yes
domain master = Yes
domain logons = Yes
wins support = Yes
ldap ssl = no
path = /Daten
read only = No
guest ok = Yes
netbios names are limited to 15 characters + 1 resource
byte. This is in line with the netbios specs. What is
the problem here?
OK, I asked our MCSE, he told me that it is possible to have longer names on a
Windows 2000 Domain Controler.
But I will check this again
Anyway, if the specs specify that Netbios Names are 15 + 1 rescource byte, than
testparm should complain about longer names, than this.
I will investigate in this again.
Jeremy has fixed issue in the netbios names.
This should be addressed in the current 3.0 cvs code.
sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
