LDAP role mapping too sensitive to extra whitespace

Using a role mapping like:

admin = karaf, test; admin = another

Will not work because the extra whitespaces are being counted towards the role names. In LDAP leading and trailing white spaces should not be counted so this should be fixed up...

Workaround is simple: just don't use any extra spaces So use a role mapping string like:
admin=karaf,test;admin=another
