I am on Univention Corporate Server 5.0.3 and installed the fetchmail from the app center a long time ago.
When I want to save changed user attributes I get the following error message, even when this user never had fetchmail configured and I do not want to change these attributes at all.
The LDAP object could not be saved: LDAP Error: Object class violation: attribute ‘univentionFetchmailProtocol’ not allowed.
I suppose that the attribute field only can have the two options IMAP and POP3. But when I change the contents I must also fill in the other parameters as Remote Server and username and password.
Pleas change the definition for fetchmaiProtocol to accept empty values.
