I had a user today that change his password..  he could still login his desktop and also login to the Filr website.. 

but it kept showing password invalid on his ipad. his password was about 21 or 22 characters long

I changed it to Password1245 for testing and it logged him right in.   then he changed the password to something around 17 characters and it also worked

I was wondering if maybe the app wasn't passing all the characters in his password..  like maybe the field is not large enough?

He did assure me he was using the correct one on the ipad.  and he did indeed use that same password on his desktop and filr web immediately after trying on his ipad.
