Pro 7.1.3 ldapsync not working

Seafile Server
1

Hi, I upgraded my test server from Pro 7.0.10 to 7.1.3. Now I tried to use the ldap sync feature, but I’m getting the following error:

[seafile@server seafile-server-latest]$ pro/pro.py ldapsync --test
Traceback (most recent call last):
  File "/usr/lib64/python3.6/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "/usr/lib64/python3.6/runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "/home/seafile/seafile-pro-server-7.1.3/pro/python/seafevents/ldap_syncer/run_ldap_sync.py", line 7, in <module>
    from ldap import SCOPE_SUBTREE
ModuleNotFoundError: No module named 'ldap'

LDAP authentication works like before. I’m on Scientific Linux 7.7.

OK, you answered this here: Seafile Server Professional Edition 7.1: Preparing the foundation for the next development stage
So, for using ldap sync I really have to switch to CentOS 8, I think.

I finally got ldap sync to work. I had to install python3-devel rpm and then I had to call “pip3 install python3-ldap” and also “pip3 install python-ldap”

# yum install python3 python3-setuptools python3-pip python3-devel -y
# pip3 install --timeout=3600 Pillow pylibmc captcha jinja2 sqlalchemy psd-tools django-pylibmc django-simple-captcha python3-ldap python-ldap

Hi,

I had the same issue on Debian 10 / Python 3.7

The manual is limited to python3-ldap
https://download.seafile.com/published/seafile-manual/upgrade/upgrade_notes_for_7.1.x.md

pip3 install python3-ldap

But with that you get this error while syncing

./pro.py ldapsync --test
Traceback (most recent call last):
  File "/usr/lib/python3.7/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "/usr/lib/python3.7/runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "/home/cc/seafile/seafile-pro-server-7.1.3/pro/python/seafevents/ldap_syncer/run_ldap_sync.py", line 7, in <module>
    from ldap import SCOPE_SUBTREE
ModuleNotFoundError: No module named 'ldap'

In you try to install python-ldap, dependencies are not satisfied

    sudo pip3 install python-ldap

Looking at the the module doc, you need some dependencies to compile python-ldap

https://www.python-ldap.org/en/python-ldap-3.2.0/installing.html#build-prerequisites

apt-get install build-essential python3-dev python2.7-dev \
    libldap2-dev libsasl2-dev slapd ldap-utils python-tox \
    lcov valgrind

For my own, i only neeeded this

apt-get install build-essential	libldap2-dev

then

python -m pip install python-ldap
./pro.py ldapsync --test

Ldap sync works now.

@daniel.pan, is python-ldap mandatory? If yes, could you update thne manual ?
