Just moved over to DA from a piece of crap called cpanel. I wrote a custom script that converted 90000 (yes, ninety thousand) accounts in a matter of hours. All accounts are now valid in DA and perfectly usable with site builder and software installer plugins which I have been providing. One-click webmail login is working perfectly well, unlike one-click login to phpMyAdmin -- stupid DA creates mysql grants for single signon user 'da_sso_xxx'@localhost (seemingly hardcoded) regardless of my remote mysql configuration, that makes an user see blank page instead of his desired list of databases. Whatever, it is not that hard to rewrite a mysql grant statement. Everything seemed well except for surprisingly idiotic logic behind SSL installation options: besides Letsencrypt and uploading own certificate, the SSL configuration page offers to install self-signed certificate and use a 'server certificate' without a possibility to disable this nonsense. I could even accept the fact of relying on that very odd Custombuild feature, which for some reason builds all the server software from sources while the same software is available in rpm/apt packages either directly from vendors or community. But I can live with that and get over almost everything else that is not worth mention. But what I can not accept is that creating a new account now takes several minutes opposite to seconds I'd had with crappy cpanel.
