With the following option selected, new users cannot be added to domains if an additional email address is supplied.
Virtualmin > Virtualmin Configuration > Advanced options > Add mail attribute to LDAP users > Yes using
mailAlternateAddress
When adding a new user with additional email address(es), this error is returned and no user is created.
Failed to save user : Failed to add user to LDAP database : mailAlternateAddress: attribute type undefined
When adding a new user without additional email address(es), the user is created and the LDAP object for the user contains a populated mail attribute.
After changing the configuration above to
… > Add mail attribute to LDAP users > Yes using only
and adding a new user with additional email address(es), the user is created and the LDAP object contains a mail attribute for the ‘primary’ email address and for each additional email address.
Also, an object is created under dc=Virtual,dc=domain,dc=tld for each email address*.
As far as I could find, mailAlternateAddress is an attribute of the MailGroup object class, but I cannot find a schema that actually includes that class. It isn’t defined in any of the schema/ldif under /etc/ldap/schema.
I found references to MailGroup here: LDAPWiki: MailGroup; and reference to mailAlternateAddress here: LDAP Attribute Reference. The latter links mailAlternateAddress to RFC 2256, but RFC 2256 (X.500) doesn’t mention mailAlternateAddress and neither do the RFCs that supercede RFC 2256.
I guess if anyone knows where that attribute is defined, that’d be useful and I can add it into my setup. In the meantime, perhaps additional text on the tooltip for the option above could warn about a potential problem.
* I was expecting to see these objects created under dc=Aliases,dc=domain,dc=tld, but I think that just shows a lack of understanding on my part.
