To use LDAPS i had to move the libnssutil3.so in Centos 7 (see LDAPS fails to contact server (LDAP works)). However, after moving the Seafile installation to a Centos 8 OS, Seafile/ccnet-server fails to start when libnssutil3.so is moved:
failed to run “ccnet-server -t”
ccnet-server: error while loading shared libraries: libnssutil3.so: cannot open shared object file: No such file
When libnssutil3.so is not moved, Seafile starts sucessfully but LDAPS does not work (same issue as in referenced forum thread). The installation is identical (ver. 7.1.3) on both Centos 7 & 8.
