Creating a truststore when using LDAP

Before you begin

Ensure that you have read the section overview.

About this task

If the connection is secured using TLS, a certificate is needed to complete the SSL handshake with LDAP. If you are connecting to multiple LDAP servers that have different certificates, you need to trust each certificate in a single trust store.

The LDAP trust store file name must be ldaptruststore.p12. It is defined using the commands in this procedure.

Procedure

Copy the certificates to be trusted to the machine where the keytool utility is installed, and stage them in a temporary directory.
Create a keystore by issuing the below command with the parameters:
```
keytool -importcert -storetype PKCS12 -keystore ldaptruststore.p12 -storepass truststore_password -alias alias_name -file file_to_trust.crt -noprompt
```
truststore_password

The desired password for your trust store. Save the password for later use.

alias_name

The value to display in the trust store, each certificate must have a unique alias.

file_to_trust.crt

The full path to the certificate you are adding to the trust store.
Optional: To import additional certificates into an existing trust store, run the below command, be sure to use a unique alias for each additional certificate.
```
keytool -importcert -storetype PKCS12 -keystore ldaptruststore.p12 -storepass truststore_password -alias aliasname -file file_to_trust.crt -noprompt
```
