I just tried upgrading to 8.0.1 server from 7.1.5 as per the instructions (installing libmysqlclient-dev, future, mysqlclient etc. in advance) - this is on Ubuntu 18.04.
After installation, none of the accounts which authenticate against LDAP would log in (either through the web interface or desktop client) - however, local seafile accounts would authenticate fine.
There was no clue in the log files what was failing.
Reverting to 7.1.5, and the LDAP accounts all work fine (i.e. not an obvious problem with the LDAP server).
Is this a known issue for 8.0.1?
