[Samba] failed to call wbcGetpwnam/wbcGetgrnam/wbcGetpwsid WBC_ERR_DOMAIN_NOT_FOUND

[Alex Matthews]

Hiya,

I've run into a problem on a Samba 4.5.8 active directory domain
controller. The domain controller seems to work to authenticate against (I
have a couple of domain members). However wbinfo throws an error when used
locally. My configs are posted at the bottom of the page.

# wbinfo -t
checking the trust secret for domain SMC via RPC calls succeeded

# wbinfo -u
<list of domain users>

# wbinfo -g
<list of domain groups>

nsswitch:
passwd: compat winbind
group: compat winbind

# getent passwd
<list of LOCAL users>

# getent group
<list of LOCAL groups>
