(ITS#8991) Error while trying to create database with attribute olcSuffix in internationalized UTF-8 DN format.

Full_Name: Varnava Sergey Version: openldap-sasl-server-2.4.47 OS: FreeBSD 12.0-RELEASE URL: Submission from: (NULL) (86.62.75.82)

slapd configured to use cn=config

I'm trying to create database under cn=config with olcSuffix attribute set to DN with international UTF-8 characters.

`cat adddb.ldif` dn: olcDatabase=mdb objectClass: olcDatabaseConfig objectClass: olcMdbConfig olcDatabase: mdb olcSuffix:: ZGM90KHQvtC70L3Ri9GI0LrQvixkYz3QlNGD0YDQlNC+0LwK olcRootDN:: Y2490JTQuNGA0LXQutGC0L7RgCxkYz3QodC+0LvQvdGL0YjQutC+LGRjPdCU0YPRgNCU0L7QvAo= olcRootPW:: e1NTSEF9ZHVyc2VjcmV0Cg== olcDbIndex: objectClass eq olcDbDirectory: /var/db/openldap-data

When doing `ldapadd -x -w secret -f /root/adddb.ldif` I'm getting this error:

adding new entry "olcDatabase=mdb" ldap_add: Invalid syntax (21) additional info: olcSuffix: value #0 invalid per syntax

Some debug from log file:
