It’s something unexpected but not abnormal 
The password is in binary form and works good on other software like Nextcloud.
The issue is inside WebTop5 SQL schema: the password field can’t handle values longer than 255 characters:
[root@mytest ~]# su - postgres -c "psql webtop5 -c '\d+ core.domains'" | grep dir_password
dir_password | character varying(255) | | extended | |
dir_password_policy | boolean | not null | plain | |
The encoded password is 693 characters long (while the plain one is 171) in my installation :
[root@mytest ~]# perl -e 'use NethServer::SSSD; my $sssd = new NethServer::SSSD(); print $sssd->bindPassword();' | java -classpath /usr/share/webtop/ WebtopPassEncode | wc -m
693
Can we expand the password field length in the initial sql? /cc @matteo.albinola @gabriele_bulfon
