3 -The guide I followed was [[https:~~/~~/wiki.debian.org/LDAP/OpenLDAPSetup#Kerberos>>https://wiki.debian.org/LDAP/OpenLDAPSetup#Kerberos]] which while it worked required some minor tweaks. I obtained edit privileges for the Debian Wiki and updated the guide with the fixes that I found. I however have a Synology NAS and that can run an LDAP Server. So this guide differs a little from the upstream Debian Guide.

5 -First, install the packages containing the LDAP-enabled Kerberos servers ([[krb5-kdc-ldap>>url:https://packages.debian.org/krb5-kdc-ldap]] and [[krb5-admin-server>>url:https://packages.debian.org/krb5-admin-server]]) and the [[schema2ldif>>url:https://packages.debian.org/schema2ldif]] tool:
6 -
7 -##$ sudo apt install krb5-kdc-ldap krb5-admin-server schema2ldif##
8 -
9 -Then load the ##kerberos## schema:
10 -
11 -{{{$ zcat /usr/share/doc/krb5-kdc-ldap/kerberos.openldap.ldif.gz | ldapadd -H ldap:~/~/nas.fqdn/ -D uid=root,cn=users,dc=example,dc=com
12 -
13 -adding new entry "cn=kerberos,cn=schema,cn=config"
14 -
15 -}}}
16 -
17 -
18 -And add an index on the ##krbPrincipalName## (improves performance and also suppresses some log messages if ##slapd## is configured to log more than default) for the database(s) where you intend to store Kerberos data:
19 -
20 -{{{# ldapmodify -H ldap:~/~/nas.fqhn <<EOF
21 -
22 -dn: olcDatabase={1}bdb,cn=config
23 -
24 -add: olcDbIndex
25 -
26 -olcDbIndex: krbPrincipalName eq,pres,sub
27 -
28 -EOF
29 -
30 -modifying entry "olcDatabase={1}bdb,cn=config"
31 -
32 -}}}
33 -
34 -
35 -Next, you need to create and configure two entries which will be used by the Kerberos servers to connect to OpenLDAP. If you are running Kerberos and OpenLDAP on the same system, these steps are optional, but recommended. In order to keep things nicely separated, everything will be created under a separate ##organizationalUnit##. Note that a simple bind (##-x -D##) is used instead of an ##EXTERNAL## bind since write access to the dc=example,dc=com DIT is necessary:
