Finally, create this Deployment for the OpenLDAP server. Also create a Service to expose the OpenLDAP
server within the cluster on the service network so the Supervisor can connect to it.

If you've saved this into a file `openldap.yaml`, then install it into your cluster using:
```sh
kubectl apply -f openldap.yaml
```
## Configure the Supervisor cluster
Create an [LDAPIdentityProvider](https://github.com/vmware-tanzu/pinniped/blob/main/generated/1.20/README.adoc#ldapidentityprovider) in the same namespace as the Supervisor.
For example, this LDAPIdentityProvider configures the LDAP entry's `uid` as the Kubernetes username,
and the `cn` (common name) of each group to which the user belongs as the Kubernetes group names.
The specific values in this example are appropriate for the OpenLDAP server deployed by the previous section's steps,
but the values could be customized for your pre-existing LDAP server if you skipped the previous section.
We'll use the CA created in the steps above to trust the TLS certificates of the OpenLDAP server.
```sh
cat <<EOF|kubectlapply-npinniped-supervisor-f-
apiVersion: idp.supervisor.pinniped.dev/v1alpha1
kind: LDAPIdentityProvider
metadata:
name: openldap
spec:
# Specify the host of the LDAP server.
host: "ldap.openldap.svc.cluster.local"
# Specify the CA certificate of the LDAP server as a
# base64-encoded PEM bundle.
tls:
certificateAuthorityData: $(cat ca.pem | base64)
# Specify how to search for the username when an end-user tries to log in
# using their username and password.
userSearch:
# Specify the root of the user search.
base: "ou=users,dc=pinniped,dc=dev"
# Specify how to filter the search to find the specific user by username.
# "{}" will be replaced # by the username that the end-user had typed
# when they tried to log in.
filter: "&(objectClass=inetOrgPerson)(uid={})"
# Specify which fields from the user entry should be used upon
# successful login.
attributes:
# Specifies the name of the attribute in the LDAP entry whose
# value shall become the username of the user after a successful
# authentication.
username: "uid"
# Specifies the name of the attribute in the LDAP entry whose
# value shall be used to uniquely identify the user within this
# LDAP provider after a successful authentication.
uid: "uidNumber"
# Specify how to search for the group membership of an end-user during login.
groupSearch:
# Specify the root of the group search. This may be a different subtree of
# the LDAP database compared to the user search, but in this case users
# and groups are mixed together in the LDAP database.
base: "ou=users,dc=pinniped,dc=dev"
# Specify the search filter which should be applied when searching for
# groups for a user. "{}" will be replaced by the dn (distinguished
# name) of the user entry found as a result of the user search.
filter: "&(objectClass=groupOfNames)(member={})"
# Specify which fields from each group entry should be used upon
# successful login.
attributes:
# Specify the name of the attribute in the LDAP entries whose value
# shall become a group name in the user’s list of groups after a
# successful authentication.
groupName: "cn"
# Specify the name of the Kubernetes Secret that contains your OpenLDAP
# bind account credentials. This service account will be used by the
# Supervisor to perform user and group searches on the LDAP server.
bind:
secretName: openldap-bind-account

apiVersion: v1
kind: Secret
metadata:

type: kubernetes.io/basic-auth
stringData:
# The dn (distinguished name) of your OpenLDAP bind account. To keep
# this example simple, we will use the OpenLDAP server's admin account
# credentials, but best practice would be for this account to be a
# read-only account with least privileges!
username: "cn=admin,dc=pinniped,dc=dev"
# The password of your OpenLDAP bind account.
password: "admin123"
EOF
```
Once your LDAPIdentityProvider has been created, you can validate your configuration by running:
