Subject: [PATCH] libnfsidmap: try to get the domain directly from hostname if
|
||||
the DNS lookup fails and always show the log message if the domain can't be
|
||||
determined
|
||||
|
||||
In nfs4_init_name_mapping(), if no domain is specified in the config file, the hostname will be looked up in DNS, and the domain extracted from that.
|
||||
If DNS resolution isn't up at this time (i.e. on idmapd startup), the hardcoded domain in IDMAPD_DEFAULT_DOMAIN is used. This will break id mapping
|
||||
for anyone who doesn't happen to use "localdomain". Previously, the log message indicating this has happened requires -v to be passed, so the
|
||||
"failure" was silent by default.
