validation_skip_attributes not working

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a user model with a userPassword attribute with a stored value like:
"{SSHA}Ni4sJ7kNRuOPErlXX9CQ/o+H0iRBnQtAje5Bwg=2"
2. Try to set any attribute on the user i.e. sn, @user.sn = 'LastName'
3. Set @user.validate_skip_attributes << "userPassword"
4. @user.update_attributes
5. Exception is thrown
userPassword has invalid format: 
"{SSHA}Ni4sJ7kNRuOPErlXX9CQ/o+H0iRBnQtAje5Bwg==": required syntax: Printable 
String: "{SSHA}Ni4sJ7kNRuOPErlXX9CQ/o+H0iRBnQtAje5Bwg=2" has unprintable 
character: '{'

What is the expected output? What do you see instead?
I would expect an ldap query that only modifies the sn attribute and not all of 
them.  ActiveLdap doesn't even execute a query against the server, it just 
blows up saying the validation failed.  It shouldn't validate the attribute 
because it didn't change anyways.  To get around this I put userPassword in 
validation_skip_attributes and it didn't change the behavior either.

What version of the product are you using? On what operating system?
1.3.7 on Mac OSx
