+#%NSS_TACPLUS-1.0
+# Install this file as /etc/tacplus_nss.conf
+# Edit /etc/nsswitch.conf to add tacplus to the passwd lookup, similar to this
+# where tacplus precede compat (or files), and depending on local policy can
+# follow or precede ldap, nis, etc.
+# passwd: tacplus compat
+#
+# Servers are tried in the order listed, and once a server
+# replies, no other servers are attempted in a given process instantiation
+#
+# This configuration is similar to the libpam_tacplus configuration, but
+# is maintained as a configuration file, since nsswitch.conf doesn't
+# support passing parameters. Parameters must start in the first
+# column, and parsing stops at the first whitespace
+
+# if set, errors and other issues are logged with syslog
+#debug=1
+
+# min_uid is the minimum uid to lookup via tacacs. Setting this to 0
+# means uid 0 (root) is never looked up, good for robustness and performance
+# Cumulus Linux ships with it set to 1001, so we never lookup our standard
+# local users, including the cumulus uid of 1000. Should not be greater
+# than the local tacacs{0..15} uids

+# To avoid server round trip delays, or worse, unreachable server delays
+# on filename completion, we include "*" in the exclusion list.
