[Owncloud] Update 5.0.7 uncontrollable encryption

[Nicolas Mora]

Hello,

Yesterday I updated from 5.0.6 to 5.0.7 without any issue, and I 
activated the encryption module to test it, but didn't do anything else 
later then.

This morning,  I saw that all my files are encrypted, without me 
knowing how, and more important, I have absolutely no idea on how to 
decrypt them, considering that I never entered any password or 
certificate for the encryption...
I only read this morning that encryption is incompatible with 
ldap_user, which of course I use...

Fortunately there is still a backup but I would like to know if the 
encryption is reversible, and how ?
