trailing characters in olcserverids after conversion

[Oliver Liebel <oliver@itc.li>]

using openldap 2.4.13 (compiled from openldap.org source-package)
i have noticed the following, reproducable behaviour when converting
a slapd.conf to slapd.d:

if slapd.conf contains serverids with ldap-urls, e.g. in this format:

ServerID        1       "ldap://ldapmaster.local.site:9000";
ServerID        2       "ldap://ldapslave.local.site:9000";

the olcserverids always contains some trailing (garbage) characters 
after the
conversion, and are base64 encoded.  when i set them manually in 
cn=config with
ldapmodify, they are displayed "clean".

the serverid-lines in  slapd.conf are "clean" (they contain no whsp/tabs 
at the end
of the line or similar, invisible chars).
i have tested it without \"\ and without portnumber,
tested conversion with slaptest and slapd,
in virtual and real machines,
result is always the same.

any ideas?

greetings,
oliver
