I have setup an OpenLDAP server and gave Confluence write permission to the LDAP. I also defined a password policy, which checks the password quality.
But when I trie to change a password, which does not fullfil the password quality requirements, I get just this error message:

This says exactly nothing altough Confluence gets a detailed description from the LDAP server, what is wrong here. This is what slapd logs:
slapd[21199]: conn=3698 op=1 RESULT tag=103 err=19 text=Bad password for dn="cn=***" because it is based on a dictionary word
Why is this information not forwarded to the user?
