Re: [Samba] Permission issue




Hi Rowland,

The user's ID range would have been below 3600, the current max rid is 3506

The links have been setup following this link, then restarted the samba-ad-dc service

https://wiki.samba.org/index.php/Libnss_winbind_Links


I followed the following to configure the winbindd stuff,

https://wiki.samba.org/index.php/Configuring_Winbindd_on_a_Samba_AD_DC


template shell = /bin/bash
template homedir = /home/%U

9833 pts/0    S+     0:00                      \_ grep --color=auto winbind
17196 ?        Ss     0:00  |   \_ /usr/sbin/winbindd -D --option=server role check:inhibit=yes --foreground
17199 ?        S      0:01  |       \_ /usr/sbin/winbindd -D --option=server role check:inhibit=yes --foreground



Regards,

Praveen

OK, you classicupgraded your NT4-style PDC to an AD DC, did your users have ID's in the '10000-999999' range before the upgrade ?

Have you set up the libnss-winbind links ?
