= LDAP Sample
This sample demonstrates how to connect to an LDAP server using bind authentication.
[[usage]]
To use the application, first run it:
```bash
./gradlew :servlet:spring-boot:java:ldap:bootRun
```
Then, request `/`, using the following credentials:
```bash
curl --user user:password localhost:8080 && echo
```
You should see a response like:
```bash
Hello, user!
```
