5 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:

7 +{{{

9 +$ sudo apt install krb5-kdc-ldap krb5-admin-server schema2ldif
10 +
11 +}}}

9 9  Then load the ##kerberos## schema:
10 10  
16 +{{{
11 11  
12 -{{{# zcat /usr/share/doc/krb5-kdc-ldap/kerberos.openldap.ldif.gz | ldapadd -Q -Y EXTERNAL -H ldapi:///

20 +adding new entry "cn=kerberos,cn=schema,cn=config"
21 +
22 +}}}
23 +
24 +
15 15  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:
16 16  
27 +{{{
17 17  
18 -{{{# ldapmodify -Q -Y EXTERNAL -H ldapi:/// <<EOF
19 -dn: olcDatabase={1}mdb,cn=config
29 +# ldapmodify -H ldap:~/~/nas.fqhn <<EOF
30 +
31 +dn: olcDatabase={1}bdb,cn=config
32 +
20 20  add: olcDbIndex
34 +
21 21  olcDbIndex: krbPrincipalName eq,pres,sub
36 +
22 22  EOF
23 23  
24 -modifying entry "olcDatabase={1}mdb,cn=config"}}}
39 +modifying entry "olcDatabase={1}bdb,cn=config"
25 25  
41 +}}}
42 +

26 26  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:
