I have upgraded a 16.04 system which worked/booted perfectly with
libnss-ldap being used by nsswitch for passwd, shadow and groups to
17.10. The system took a long time to boot, could not bring up
networking properly (running dhclient in 90 second intervals, possibly a
timeout) and could not start systemd-logind.
After using nss_initgroups_ignoreusers as stated by Graham Eames in #14
and adding a new line as suggested by Thomas Werschlein in #24, the
system started bhaving normally again.
You can use the following command, which I stole from stackexchange, to
populate the nss_initgroups_ignoreusers paramter automatically:
#NSS_IGNOREUSERS="$(cut -d: -f1 /etc/passwd | sort | tr '\n' ',' | sed
's|,$||')"
#sed -i "s|^nss_initgroups_ignoreusers.*|nss_initgroups_ignoreusers
${NSS_IGNOREUSERS}|" /etc/ldap.conf
However you will have to add a new line afterwards!
In short: This issue affects 17.10, too.
Suggestion: libnss-ldap should have a paramter which makes it check the
passwd/group files and using names which are in there in the
nss_initgroups_ignoreusers paramter automatically. This should also be
the default configuration, since systemd is the default also.
