[Samba] Samba 4.5.3 AD DC - issues with sysvol when setting up Group Policies

[Richard]

Hi Rowland,

100% ! I hadn't set up the libnss_winbind links.

I have now done this using:

# ln -s /usr/local/samba/lib/libnss_winbind.so.2 /lib64/
# ln -s /lib64/libnss_winbind.so.2 /lib64/libnss_winbind.so
# ldconfig

When I test as follows all looks good:

root at dc1:~ # wbinfo --ping-dc
checking the NETLOGON for domain[CT] dc connection to "dc1.ct.mydomain.com" succeeded

but for some reason I don’t understand "getent" still doesn't work when executed on the DC

root at dc1:~ # getent passwd richard.h
root at dc1:~ #

If I do the same on one of the domain members  it works fine...

root at office1:~ # getent passwd richard.h
richard.h:*:10010:10001::/home/ richard.h:/bin/bash


I'm pretty sure I'm doing the same pam / nsswitch setup on the DC as I did on the domain members (not sure whether relevant but the domain members are running standard CentOS 7 Samba 4.4.4 packages)

do you possibly have any idea why getent isn't working on the domain controller? 

thanks!

I have thought about this and notice that you gave 'Domain Admins' a gidNumber (which you have now removed), but 'getfacl' only showed the number not the group name. This makes me wonder if you have set up the libnss_winbind links etc. If you haven't, or don't know what I mean, see here:
