Data-Curruption would only happen if a User or User + Myself updated the password at the same time.
I honestly didnt realise this fuction was included, that will teach me to wear my glasses ALL the time
But, I still need ONE system for the Users, the main functions they must have are FTP - MAIL - User admin.
Currently WebFTP does not work with my ISPConfig Installation, otherwise I would have used that with a Webmail Plugin.
Thats why I asked, so if you have any tips for Horde, please, I am all ears
