This is wrong and causes a set of use cases of ldap attribute map code to fail. Patch forthcoming.
Created attachment 196855 [details] [diff] [review] patch, v1 Explicitly don't check for multiple null-valued attribute-lists when sanity checking an attribute map.
Fixed on the trunk. Requesting approval for the 1.8 branch, as this bug severely curtails the usability of the LDAP attribute map, and the fix is low risk.
