I turned on logging in data/conf/sogo/sogo.conf, in the container logs I see a connection to the database and an attempt to pull out a password like: SELECT c_password FROM _sogo_static_view WHERE c_uid = ‘user @хх.хх’;
Connected to the database, users are present in the database table:
user@xx.xx | xx.xx | user@xx.xx | {MD5}ZVN1hovmmV34NCxjRKIDVw== ….. There is ldap-md5 hash (Base64 encoded hash)
The table contains users whose passwords are hashed {BLF-СRYPT}хххххх - for such users the SOGO login works normally.
