Using Version: 0.4.11 r5663
If you leave the "ldap server port" field empty the error message that gets shown to the user is not clear enough as to what he did wrong.
How to replicate:
1) Login to drake cms
2) Go to System > Drabots Manager
3) Find the LDAP Authentication Drabot
4) Click on it to edit it
5) Leave the "ldap server port" field empty
6) Click on save
An error message will come up saying "Minimum allowed length is 1". This error message is not clear enough. The error message that should come up should be informing the user that a required field has not been filled and
not what the minimum length is.
