3	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.

6	6	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:

11	11	Then load the ##kerberos## schema:

15		-##{{{adding new entry "cn=kerberos,cn=schema,cn=config"}}}##
16		-##{{{$}}}##
	16	+{{{

	18	+$ 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
18	18
19		-Having 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. As this is OpenLDAP on the Synology, it does not use ##mdb## format, it uses ##bdb##:

21		-##{{{$ sudo ldapmodify -H ldap://nas.fqhn/ -D uid=root,cn=users,dc=example,dc=com -W <<EOF}}}##
22		-##{{{dn: olcDatabase={1}bdb,cn=config}}}##
23		-##{{{add: olcDbIndex}}}##
24		-##{{{olcDbIndex: krbPrincipalName eq,pres,sub}}}##
25		-##{{{EOF}}}##
26		-##{{{Password:}}}##
27		-##{{{modifying entry "olcDatabase={1}bdb,cn=config"}}}##
28		-##{{{$}}}##
	22	+}}}

31		-Next, you need to create and configure two entries which will be used by the Kerberos servers to connect to OpenLDAP. As you will not run the Kerberos KDC and Admin Server on the same host as OpenLDAP, these steps are required. In order to keep things nicely separated, everything will be created under a separate ##organizationalUnit##.
	25	+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:

33		-##{{{# ldapadd -H ldap://nas.fqhn/ -D uid=root,cn=users,dc=example,dc=com -W <<EOF}}}##

	44	+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:
