Hello,

after upgrade to Seafile 9.x the LDAPS connection to our LDAP servers does no longer work, even with the move of

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

We found that when we move

```
libgmp.so.10 libgnutls.so.30 libhogweed.so.4 libidn2.so.0 libp11-kit.so.0 libtasn1.so.6 libunistring.so.2
```

it seems to work at least under Debian 10.

Does the documentation need to be updated?
