As long as all the maps are returned, though, this is really only a
confusing error message. I think the code that causes it is in SSSD's
automounter client code, around line 172 with the current master:

172 if (len == 0) {
173 /* There are no more records. */
174 *_key = NULL;
175 *_value = NULL;
176 ret = ENOENT;
177 goto done;
178 } 

what you see in the output is just strerror(ENOENT)..

The mount work fine actually. I only noticed the error because I have
a script that is consuming the standard output from "automount -m"
command.  I thought instead of filtering away the error, it would be
more prudent to fix the root issue.

Now that I have shared some context, is there any way I can track down
whats might be causing it? Or better, whats are some of the candidate
mistakes that can trigger it.

No idea without more context, sorry. Does auto mounter actually work for you or 
are some maps missing?

The message can really be harmless, because the client (=automounter) iterates 
over the maps returned by the server (=sssd in this context) until the server 
returns ENOENT. I agree though the message is confusing and we’ll be (most 
probably) looking at some autofs enhancements in the next sssd version..

[Freeipa-users] mount lookup failure getautomntent_r

[William Muriithi]

Hello,

I have noticed an error that pop up as the final line after running
this command "
automount -m". I suspect its related to selinux, but haven't seen how
to fix it from the google search this morning.

I have autofs maps on IPA and using SSSD to read the maps.


Mount point: /-


source(s):

lookup_read_map: lookup(sss): getautomntent_r: No such file or directory

  failed to read map

Have anyone found a way to clean up that error?

Regards,
William
