NFSv4 in RHEL/CentOS 6.x uses libnfsidmap as a sort of add-on module. I
believe the package you need is nfs-utils-lib.

Content of idmapd.conf:
As long as idmapd is *running* it typically doesn't need to be
configured specifically.
Now one more question. The imap daemon is a mail server. How is it
that I need a mail server running to make LDAP and NFS work? Doesn't
seem to make sense to me.
idmapd is not imapd. idmapd (aka rpc.idmapd) is a helper for NFSv4
which should be run on the server. It shouldn't be required on the
client.
A couple of points: 1) Your original message isn't specific about the
problem that you're seeing, but if idmapd is involved, then the
problem isn't related to LDAP. NFSv4 will work the same way whether
you're using NIS or LDAP. Pretty much everything other than NSS and
PAM will, in fact. 2) I don't recommend rolling your own LDAP
services. It's very easy to let sensitive information leak. Using
FreeIPA for LDAP and KRB5 is much easier and a lot more secure.
Thank you for your reply to my incompetent query.
Okay, I'm a bit dyslectic. I see that I should have seen idmap but I
saw imap. I missed the "d". That leads me to another question:
I don't see a package that contains idmapd. When I try to install it I
get:
No package idmapd available.
No package idmap available.
I don't see idmapd in the Service Configuration GUI.
rpm -qa | grep idmap
libsss_idmap-1.13.3-60.el6_10.2.x86_64
How might one install a daemon by the name idmapd on CentOS 6?
