I have emerged OpenLDAP and phpldapadmin.
I then configured the ldap.conf and slapd.conf using the Gentoo howto: http://www.gentoo.org/doc/en/ldap-howto.xml
as a guide.

But when i try to start the slapd deamon I get this error:
Quote:
fserver ~ # /etc/init.d/slapd start
* Starting ldap-server ...
* start-stop-daemon: failed to start `/usr/lib64/openldap/slapd' [ !! ]
* ERROR: slapd failed to start


When I run the slaptest I get this:
Quote:
fserver ~ # slaptest
51dd4ac4 hdb_db_open: database "dc=nismoc32,dc=local": db_open(/var/lib/openldap-data/id2entry.bdb) failed: No such file or directory (2).
51dd4ac4 backend_startup_one (type=hdb, suffix="dc=nismoc32,dc=local"): bi_db_open failed! (2)
slap_startup failed (test would succeed using the -u switch)


If I use the -u switch it reports everything is OK.
Quote:
fserver ~ # slaptest -u
config file testing succeeded

The /var/lib/openldap-data folder was created by portage and has the correct owner and rights.

I have searched for a solution on this problem online but havent had any luck so far.
Is there anyone here who can shed some light on whats wrong :?:

Have you set the ownership of both /etc/openldap and /var/lib/openldap-data and its contents to ldap.ldap.
Also check if /run/openldap exists.

Thanks for the input hika.

It turns out that the owner for the files in the openvpn-data was owned by root, despite the folder was owned by ldap.
After I changed the owner/user to ldap for all the files under the /var/lib/openldap-data folder everything worked.

Thanks.

That happens always when you add ldifs with slapadd, for it runs as root. Slaptest won't complain for you also run it as root.
So always after you add data wih slapadd, reset the ownership! It's a quit standard starter fault.
