A Container is created for Provider from PCC under
Top > Service Director > Virtuozzo Manager > Containers
The Container's hosting plan includes Plesk application.
Upon the Plesk application installation the Psa_password_reseting task fails with the message
Psa_password_reseting Container domain.tld
where domain.tld is a domain name set for the Container in question.
Clicking on Redo tasks resolves the issue.
Such behaviour is classified as the software issue PBAS-25226 and will be fixed in future OBAS releases.
