[xwiki-users] question about ldap authentication

Hi, On Xwiki 6.2.1, I use xwiki.authentication.ldap.fields_mapping parameter in xwiki.cfg. Are there a way to concatenate two ldap fields? By example, I have two LDAP field for adress (street and town) and I want concatenate them in the xwiki address field from XWiki User Class. Thanks Pascal B
