Here is nsswitch.conf:
group:          files ldap
group_compat:   nis
hosts:          files dns
netgroup:       files [notfound=return] nis
networks:       files
passwd:         files ldap
passwd_compat:  nis
shells:         files

user slapd and group ldap are resloved locally:
in /etc/passwd
slapd:*:402:497:openldap-server slapd user:/nonexistent:/sbin/nologin

in /etc/group
ldap:*:497:

$ id slapd
uid=402(slapd) gid=497(ldap) groups=497(ldap)

Here is the backtrace (the bottom is not very helpful, but fortunately
there is only one occurence of initgroups in slapd sources)
