Actually I solved the problem meanwhile by using FQDNs (altough i don't
really see why is it important on a local-network) and trailing slashes jus=

as you have suggested.
The version is exactly:
$ slapd -VV

Okay, i found the bug.<br>
It was about the olcServerID.<br>
My cn=3Dconfig showed olcServerID: 1 ldap://alpha-int/, olcServerID: 2<br>
ldap://beta-int/, which is correct.<br>
But if I start my openldap as ubuntu says (/usr/sbin/slapd -h<br></div>
ldap://beta-int/ ldap://<a href=3D"http://127.0.0.1:389/" target=3D"_blank"=

>http://127.0.0.1:389/</a>> ldapi:///<div class=3D"im"><br>
-g openldap -u openldap -F /etc/ldap/slapd.d/), it does not recognise<br>
that he is beta-int. Only if I start it with only the ldap://beta-int/<br>
parameter. But I really need the other two interfaces as well.<br>
What can I do now with it?<br>

<br>
What version of OpenLDAP are you using?<br>
<br>
A bug similar to this was corrected in 2.4.18:<br>
<a href=3D"http://www.openldap.org/its/?findid=3D5942" target=3D"_blank">ht=
tp://www.openldap.org/its/?findid=3D5942</a><br>
<br>
If you're using an older version, this should still work fine so long a=
s the URL in the -h option to slapd exactly matched the URL in serverID (ma=
ke sure the all slashes are present, etc).<br>
<br>
Preferably, use the latest release, though, to avoid other such bugs now fi=
xed :)<br>
