In Safeguard for Passwords 6.9, when modifying or viewing directory attributes, and an attribute is mapped more than once then the following error is thrown.
Invalid schema UserProperties mapping: The same attribute cannot be mapped for multiple properties (60407)
In v6.8 and lower it is possible to set attributes to use the same value eg. UserPrincipalName without issue.
**Note userPrincipalName is populated for "email" and "External Federation Authentication"
The problem is using the userPrincipalName in the email attribute field. In 6.9 the alt-login-name attribute for asset directories was added and has been used as default - userPrincipalName. Directory IdentityProviders do not use this property and so it is not shown in the UI but internally it is still being mapped to userPrincipalName and so we see this conflict.
Issue fixed in 6.10.
