Problems with Testuser

[ghellstern]

I wanted to to try HAWKI in a simple local setup with a testuser.

In .env I therefore specified:

Authentication="LDAP"
# LDAP config
#LDAP_HOST="ldaps://..."
#LDAP_BASE_DN="cn=...,ou=...,dc=..."
#LDAP_BIND_PW="..."
#LDAP_SEARCH_DN="ou=...,dc=..."
#LDAP_PORT=""
#; Choose the filter based on your LDAP configuration. the value "username" is used as a placeholder and will be replaced with the actual #username in authentication function.
#; EXAMPLES:
#; (|(sAMAccountName=username)(mail=username))
#; (|(uid=username)(mail=username))
#LDAP_FILTER="(|(sAMAccountName=username)(mail=username))"

# Testuser accout
TESTUSER="test"
TESTPASSWORD="test"

When submitting the login and the password the following error appears on the web-server:

[::1]:58325 [500]: POST /login - Uncaught Error: Call to undefined function ldap_escape() in C:....\HAWKI\private\app\php\auth.php:138
Stack trace:
#0 C:...\HAWKI\private\pages\login.php(17): require_once()
#1 C:....\HAWKI\index.php(18): include_once('...')
#2 {main}
thrown in C:...\HAWKI\private\app\php\auth.php on line 138

Any idea whats going wrong??

Thanks a lot for a hint!!

Did you install the dependencies via composer? See https://getcomposer.org/doc/01-basic-usage.md and https://github.com/HAWK-Digital-Environments/HAWKI/blob/main/composer_install.sh for details.

php composer.phar update

Hey @ghellstern,
did you try @ItsNotYou's suggestion?
I've never had this issue myself. Ldap escape is already in php 8. you can check here for more info.
but the code itself is meant to prevent code injection. I think if you comment out the line, you can still test the rest of the project.

Hi @Adriansdf!
The hint by @ItsNotYou unfortunately did't help - but commenting out the line with Ldap escape did :-) Since I want to test only locally, it will not harm...
Thanks a lot for your support !

Hi @ghellstern,

I ran into the same issue when dockerizing HAWKI for local development. In my case, my PHP-image (8-bullseye) was missing libldap2-dev and the LDAP extension. Depending on your setup, you might want to try and install those to fix the issue.

@ShUl0w: Would you mind sharing your Docker instructions?

[ShUl0w]

Hi @DanielBarie,

sure, I set up a basic repository with a working php-apache based Dockerfile for HAWKI. Please note that this is not equivalent to what I'm using for local development, which is a bit more involved.

@Ariansdf I don't know if its any help for the project, but maybe it would be a good idea to provide a docker image / documentation for trying HAWKI locally for the less tech-savy?

@ShUl0w: Appreciate! Makes life a little bit easier.

@Ariansdf: Would you mind extending the readme for more detailed setup instructions? Or maybe have a Wiki?

[Ariansdf]

@ShUl0w
I'm sure Docker will facilitate the deployment process and we will definitely include it in our next main release.
Unfortunately at the moment I don't have the capacity but our colleagues at Hochschule Munich and Cologne University are working on it.

I'm working on a detailed documentation for the next main release.

@Ariansdf Awesome; in case I can be of help, feel free to reach out. I will keep my repo up until there's an official image / documentation, and dispose of it once those are implemented.

That sounds fantastic!
