There are duplicate keys in synchronization

[Chf]

When synchronizing with aad, duplicate key is found. If two hash values are the same when the HashMap method is invoked at the bottom of crowd, what is the solution?

Hi @Chf 

My guess is that you have multiple Azure AD groups that share the same displayName, haven't you?

As per Atlassian's documentation

In Azure AD, you can have multiple groups with the same name (displayName), but it's not supported in Crowd and results in a failing synchronization. Make sure you change your Azure AD group names to unique ones.
