PassCore using Docker always got Invalid Credentials

[emper0r]

PassCore Server

• OS: [ Linux ]
• Provider: [ Active Directory ]
• Settings file (without sensitive information): appsettings.json below
• Log file (without sensitive information):

Describe the bug
Hi, thanks for the community free project but i'm still trying to figure out HOW can connect this docker container with Active Directory, I read ALL open issues, to verify the other solutions, I read almost ALL issues closed to implement the combination explained with different versions and appsetings.json. but NOTHING .... not exist any way to can talk with LDAP Active Directory from Docker.

To Reproduce
Steps to reproduce the behavior:

1. Fresh install from Almalinux (RedHat Enterprise Linux clone)
2. install docker engine
3. clone the latest version from master, (i test it even 4.2.4, 4.2.3 with little modifications)
   the rest of tags are too old to build now and get more errors

cd /usr/local/src
git clone https://github.com/unosquare/passcore.git passcore
cd passcore
vim Dockerfile

remove this line https://github.com/unosquare/passcore/blob/master/Dockerfile#L15
modify the line https://github.com/unosquare/passcore/blob/master/Dockerfile#L16 without --no-restore otherwise NEVER build an image correctly

vim /usr/local/src/passcore/src/Unosquare.PassCore.Web/appsettings.json
docker build --rm -t passcore .
docker run \
-e AppSettings__LdapUsername='Administrator' \
-e AppSettings__LdapPassword='StrongPassword' \
-it -p 8000:80 passcore:latest

Expected behavior
Change the password of user

Screenshots

Desktop (please complete the following information):

• OS: [Windows]
• Browser [Chrome]
• Version [latest]

Additional context
I want to add this info, I made research about LDAP Novell client to check if some special chars how would be parser to set correctly and then review the code and seems ok. so in theory passcore clean very well the special chars but including changing the administrator password to a simple 123abc just for test, the container NEVER connect... always said. Invalid Credentials.

network communication are fine and can check here in both ports 389, and 636 but still research. the password in Active Directory NEVER change using 389 because require secure port so always have to use 636.

i don't know what other things need to do and verify or check to try use this software, we don't use Windows to install an IIS and deploy this.. we need to use docker as microservices.

any help please!? is very frustrating...

I'm not sure, but if I understand the following passage from the Readme correctly, then this means that MS Active Directory is not supported with Linux (and with that docker):

PassCore was created to use the Microsoft Active Directory Services provided by .NET Framework, but a new Provider using Novell LDAP Client can be used instead. This provider is the default when PassCore is running at Linux or macOS since Microsoft AD Services are NOT available.

For me it works with MS AD with passcore running in docker container.

According to the container log, passcore cannot connect to the LDAP server. Maybe you don't have SSL configured for AD?

[emper0r]

Hi @drbogar yes. in fact after other research i had to installed AD Certificate role to enable this in the AD, and making testing using ldp.exe in the AD and now can see certificate works on MS AD,

After that i exported the certificate and import from .DER converting into .PEM to our server linux as updating root-ca but maybe must be imported inside the container itself ?? but still getting error.

the new one is certificate is rejected.

can you provide me your the steps after MS AD are the RootCA created it. maybe I'm misssing something in the middle process.

something like,
export certificate, and do this commands on linux... etc.

[drbogar]

Yes, you must install the AD RootCA certificate as a trusted CA.
The container is a separate computer in this respect.

1. export the RootCA certificate in crt extension format.
2. copy the exported CA certificate into the /usr/local/share/ca-certificates/ folder of the docker container:
   Add these two lines (modified as appropriate) to the Dockerfile:

ADD your_ca_root.crt /usr/local/share/ca-certificates/foo.crt
RUN chmod 644 /usr/local/share/ca-certificates/foo.crt && update-ca-certificates

I hope this helps.

Hi @drbogar
thanks for the steps..
I'll did exactly and still getting error from passcore.

my steps was:

connect to MS AD
execute wizard to extract RootCA - copied into Download as dc1.domain.local.der
download and upload into docker engine linux.
run this commands to convert it

openssl x509 -inform der -in dc1.domain.local.der -out dc1.domain.local.crt
cp -v dc1.domain.local.crt /usr/local/src/passcore/

modify the Dockerfile with your instructions and build but still with error below

here is the log

[drbogar]

I see... 🤔
Can you show me how the Dockerfile looks after editing?
What is the result of running the following command on your docker host?:

docker exec -it <name of the passcore container> ls -lta /etc/ssl/certs | grep -i dc1.domain.local.crt

[emper0r]

Hi @drbogar sorry by delay, I did that grep and don't show up the certificate... must be appears under /etc/ssl/certs ?
in the dockerfile i set copy to dir /usr/local/share/ca-certificates/ after update-ca-certificates command maybe moved but isn't in that directory were was filter.

i guess must be add 1 not 0...

after docker build when i start the container passcore inside not exist the certificate file inside.

can you try to copy to /etc/ssl/certs instead of /usr/local... ?

The certificate should be placed in /usr/local/share/ca-certificates/. The update-ca-certificates command copies it to /etc/ssl/cert.

Extract from the update-ca-certificates command man page:

update-ca-certificates is a program that updates the directory /etc/ssl/certs to hold SSL
certificates and generates ca-certificates.crt, a concatenated single-file list of
certificates.

Passcore's Dockerfile creates several temporary images during the build. Each FROM is the start of a new image. To install the RootCA certificate on the final container, you need to insert the two lines I wrote earlier after the last FROM.
I hope this helps.

[emper0r]

Hi @drbogar

I set the line after last FROM, now the certificate was added, but have to set absolute path for the command /usr/sbin/update-ca-certificates

 ---> Running in d9d2899d03e8
Updating certificates in /etc/ssl/certs...
1 added, 0 removed; done.

in fact now with grep I can see it inside the container, but still getting error rejecting certificate this is weird.

I test the certificate with other software and the test show "LDAPS certificates looks good"

this is the output certificate

any other idea?
can you share appsetttings hidding only sensitive data.??

are you using the last code here from master branch?

[emper0r]

if I add this option

-e AppSettings__LdapIgnoreTlsErrors='true'

seems to works saying passowrd was changed BUT I see in the logs never connected to AD, so I assume this is only for test purpose for validate only the web form because never changed the password and with false try to connect with that certificate error reject again.

[emper0r]

any update?
