Plesk removes the IUSR_ and Domain User as asked by .security

[Inspiring]

Hi all,

I have experienced this problem on two different machines since this week. Clients complain that after change of FTP account of a website, the website immediately requires ACL login. On inspection, the IUSR_ and Domain User is removed from httpdocs .

I have tried both ftpmng.exe http://kb.odin.com/en/549 and plesk reconfiguration module - repair Plesk installation - Plesk Virtual hosts Security, both does not fix the problem.

I have noticed that the .security file in the affected site is very small compared to other sites, and in it there is no mention of IUSR_ .

So my question is, does anyone know how to repair the .security file, and what could cause Plesk to generate currupt .security file?

Thanks!

Ok Problem partially fixed - but deleting the .security file and re-run plesk reconfiguration module - repair Plesk installation - Plesk Virtual hosts Security

This create the correct .security file!

However I still don't know what caused the problem with .security. Any one have any ideas?
