LDAP Broken under Seafile 8.0.1 Server

[nicu]

I managed to install the 8.0.5 version on my laptop, architecture AMD64, and it is working!

I copied the seafile configuration from the instance I am running on raspberry, which means it connects to the same database (MySQL) and the same LDAP server. I even installed the exact same packages (I am running it inside Docker container that I am building myself).

Since the only difference between the 2 instances is in the binaries, I can conclude that there is something different in the ARM ones.

@jobenvil, is there any more information I can provide? Now that I have 2 instances that I can compare

@nicu thanks for asking! You could compare:

dpkg -l | grep -i ldap
ldd seaf-fuse seaf-server (directory i.e. /home/seafile/seafile-server-8.0.5/seafile/bin)

and check this also, but I think you already know about it:

Seahub's database connection fails when LDAP-related libs are removed

I have a mostly working Seafile setup on an Ubuntu 20.04. I could reproduce the following with the releases 8.0.3 and 8.0.5. As suggested in the manual, I have to remove the files …/seafile-server-latest/seafile/libs/{liblber-2.4.so.2,libldap-2.4.so.2,libsasl2.so.3} to get connections to the LDAP server working. However, with these files removed Seahub stops working and guessing from the following stack trace, it seems that the database connection doesn’t work anymore: seahub.log 2021-05-20 …

and here the seafile “manual”:

https://manual.seafile.com/deploy/using_ldap/

[nicu]

thank you @jobenvil for taking so much of your time to look into this issue!

I did some more investigation based on the info you provided.
ldd seaf-fuse seaf-server - I pasted at the end of this post the results of running command in both arm and amd installations (sorry for posting the here, I could not find a way to attach them as files)

what I noticed is that those 3 ldap libraries mentioned in the manual and the linked post,

liblber-2.4.so.2 libldap-2.4 .so.2 libsasl2.so.2

are not listed as dependencies in the arm instance but they are in the amd

additionally, I noticed that in the folder /opt/seafile/seafile-server-8.0.5/seafile/lib I have

• for arm
  liblber-2.4.so.2 libsasl2.so.2 libldap_r-2.4.so.2
• for amd
  liblber-2.4.so.2 libsasl2.so.2 libldap-2.4.so.2
  notice the _r for libldap - not sure if this makes any difference since they don’t seem to be used, based on the below list of dependencies

@nicu we have to thank you.

It is good that you read the linked post. The key is in these three libraries. In some cases Seafile recommends to move them to another directory and then the seafile binaries will use the libraries from your system and not the linked one. Why? because they compile with a specific environment, BUT we compile (or myself) with native binaries. It does means, that I build the seafile binaries inside a “focal”, “bionic”, “buster” and “stretch” lxc containers. Our linked build binaries have literaly the same libaries that would have by default the system, therefore this garantee some libraries coherence.

I observe something different between your posted arm libraries and mine:

I would dig why your seaf-fuse and seaf-server binaries have no link to the libldap_*, liblber* and libsasl2

[jobenvil]

@nicu did you compile by yourself or did you download the binaries from Github?

If you downloaded from GitHub, which distro do you have?

[nicu]

I downloaded the binaries from Github.
The distribution I am using is Debian Buster - I am installing Seafile in a Docker container based on debian:buster-slim

Aside from the seafile binaries, I am installing the following system packages

apt-get install -y \ 
        default-libmysqlclient-dev \
        memcached libmemcached-dev \
        python3 \
        python3-setuptools \
        python3-ldap \
        python3-pylibmc \
        python3-urllib3 \
        ffmpeg \
        python3-pil \
        python3-pip \
        python3-pymysql \
        python3-memcache \
        python3-requests; \

and then python packages

pip3 install requests_oauthlib Pillow captcha jinja2 sqlalchemy django-pylibmc django-simple-captcha future mysqlclient

[jobenvil]

@nicu I found the issue. It turns out that I uploaded an “old” v8.0.5 build and therefore not linked the ldap libraries to the binaries. Thanks to your posts it was possible to discover the problem

I built again all the 4 distros. They are already uploaded. Please check now

[Josue]

Now it works. Thanks a lot

[nicu]

It also works for me!
Thank you @jobenvil and everyone else for your time and effort!

[jobenvil]

@nicu Sure, we are the Seafile community
