[Samba] No write access on new shares until smbd is restarted

[Eugene Pankov]

Rowland,

Sorry - here are the globals and share config:

[global]
template shell=/bin/bash
log file=/var/log/samba/log.%m
log level=8
max log size=5000
passdb backend=tdbsam
load printers=no
printing=bsd
printcap name=/dev/null
map to guest=bad user

[2430_ram]
path=/data/fs/2430-ram
guest ok=no
browseable=yes
create mask=0775
directory mask=0775
read only=no
follow symlinks=yes
wide links=no
valid users=man_dude
oplocks=yes
locking=yes

The log from my first message is a user attempting and failing to create a
folder in the root of the share. The user is the one specified in
valid_users.

The OS level permissions are correct - i.e. I can log in locally as
man_dude and create that folder on the FS.

Let me know if there's other info you could use.

Eugene
