I've come accross a couple of bugs to do with LDAP accounts:
I'm logged in with my AD(LDAP) account I click Profile up the top right and it doesn't display First or Last name. also when I click edit it comes up blank.
When i assigned myself as a backend user I had to enter these in. and if I find myself via the users page they are still there.
User grid paging doens't seem to be working quite right.
21 users showing on each page. the 21st person is always the first person on the next page.
Doesn't always happen going from 10 to ... (11), 20 to ...(21) etc, but it does always happen on every other page 11 to 12, 33 to 34 etc.
