To try and identify the problem, can I ask - when you say slapd doesn't start,
how long have you waited?
There is a chicken-and-egg problem with slapd on a host which is running
nss_ldap. To start a process, the system has to adopt the user and group
privileges of the process owner, which means enumerating all the groups for
that user from every source of group information - including LDAP on a system
So, to start slapd, the system needs the group info for user ldap - from
slapd. It times out and retries a few times, and eventually starts slapd
using the group information from /etc/passwd and /etc/group, but the timeout
and retry options by default take several minutes.
The delay can be even longer depending how many other services are being
started first and therefore how many nss_ldap lookup timeouts occur during
There are a number of possible solutions depending which version of nss_ldap
you're running - searching for nss_ldap bind_policy nss_reconnect_tries will
produce a number of suggestions and ``problem reports''.
