I have done like You said. Here is output:

[root@nfsclient ~]# automount -vvvf
1  Starting automounter version 5.1.1-3.fc23, master map auto.master
2  using kernel protocol version 5.02
3  mounted indirect on /misc with timeout 300, freq 75 seconds

7  attempting to mount entry /home/afayzullin
8  >> mount.nfs4: Connection timed out
9  mount(nfs): nfs: mount failure nfserver.ciktrb.ru:/home/afayzullin on
/home/afayzullin
10 failed to mount /home/afayzullin
11 re-reading map for /home
12 attempting to mount entry /home/afayzullin

from string 1 till 6 is startup output. I have googled by
'getautomntent_r', it has shown some closed threads that should be fixed
(line 3, 4, 5 shows that it is ok)
from line 7 I try to login as afayzullin and autofs tries to mount it as
I wish, but for some reason it can not.
How can I know why it can not do it? Where to look for it?

also I have put debug_level=6 in [autofs] at /etc/sssd/sssd.conf and
here is a piece from /var/log/sssd/sssd_autofs.log

While manual mount works fine:
# mount -vvv -t nfs4 nfserver.ciktrb.ru:/home/afayzullin /mnt
mount.nfs4: timeout set for Tue Jun  7 17:07:25 2016

$ ssh nfsclient

So what steps should I take next?
