one user can't be looked up

[Peter Moody]

this is admittedly low priority since this is all just a test network
at this point, but we're looking to deploy sssd at work so I'd like to
make sure all the kinks I know about are well understood/fixed

I have an openldap install with the following users (pmoody, peter)
with uidNumbers (1001, 1002) respectively.

sssd works for both users from freebsd 11.2 prelease (sssd-1.11.7_11,
whew, that's old).

sssd works for pmoody from debian stretch (1.15.0-3). it does *not*
work for the user peter.

this is what happens for the user peter.

pmoody@deb:~$ sudo sss_cache -E
pmoody@deb:~$ getent passwd pmoody
pmoody:*:1001:500:Peter Moody:/home/pmoody:/bin/bash
pmoody@deb:~$ getent passwd peter
pmoody:*:1001:500:Peter Moody:/home/pmoody:/bin/bash
pmoody@deb:~$

I've tried version 1.16.1-1, same results.

These are the ldap entries for the aforementioned users:

# peter, people, x.com
dn: uid=peter,ou=people,dc=x,dc=com
cn: peter
givenName: peter
sn: moody
uid: peter
uidNumber: 1002
homeDirectory: /home/peter
objectClass: top
objectClass: posixAccount
objectClass: shadowAccount
objectClass: inetOrgPerson
objectClass: organizationalPerson
gidNumber: 500
loginShell: /usr/local/bin/fish

# pmoody, people, x.com
dn: uid=pmoody,ou=people,dc=x,dc=com
cn: Peter Moody
givenName: Peter
sn: Moody
uid: pmoody
uidNumber: 1001
homeDirectory: /home/pmoody
objectClass: top
objectClass: posixAccount
objectClass: shadowAccount
objectClass: inetOrgPerson
objectClass: organizationalPerson
loginShell: /usr/local/bin/fish
gidNumber: 500

on the debian box that exhibits this error, I see the following in the logs:

it kind of looks like what was reported here :
https://lists.fedorahosted.org/archives/list/[e-mail].o...

but I don't see a resolution to that report.

any suggestions on what I can do to fix this? logs/configs I can
provide to help isolate the problem?

Cheers,
