Comment 2 for bug 1414507

I found a workaround that shuts libnss up; the following settings in /etc/ldap.conf were:

    nss_initgroups_minimum_uid 0
    nss_initgroups_ignoreusers root

I changed:

    nss_initgroups_minimum_uid 30

then used usermodify to shuffle the syslog user uid (it was 120ish):

    usermodify -u14 syslog
    groupmodify -g14 syslog

I then re-populated nss_initgroups_ignore_users using:

    service libnss-ldap restart

giving:

    nss_initgroups_ignoreusers
bin,daemon,games,lp,mail,man,news,proxy,root,sync,sys,syslog,uucp

This shut libnss_ldap up and stopped the log from hanging.
