Bug 307144

Using an LDAP resource for the address book with an user who has a colon in its password, the credentials are constantly mixed up, because parts of the password are used for the user's name.

Reproducible: Always

Steps to Reproduce:
1. Create an LDAP resource and connect with an user that has a colon in its password
2. Start Kmail, create a new email and start typing in the address field
3. Auto-completion tries to access the LDAP, fails and a dialog appears to enter user name and password
4. Enter correct values, check box to save values and press OK
5. Auto-completion worked, results are visible in the drop-down box
6. Press next character

Actual Results:  
LDAP dialog appears again (obviously LDAP connection failed again) and this time the dialog field for the user contains additionally parts of the password as default

Expected Results:  
It should have been possible to establish the LDAP connection again without problems

Example connecting to an Active Directory server with LDAP:
- Username: "DOMAIN\me"
- Password: "my:pwd"

The dialog will use later as wrong defaults:
- Username: "DOMAIN\me:my"
- Password: "pwd"

It looks like that some component has problems with URL encoding and/or URL interpretation. The LDAP URL should be something like:

ldaps://DOMAIN%92me:my%58password@host:port/...

However, if some component fails to URL encode the values, you get:

ldaps://DOMAIN\me:my:password@host:port/...

In this case it is now moot to guess how this URL has to be interpreted, but the wrong default values in the LDAP dialog get obvious.

Since the LDAP connection works right directly after entering the proper values, the error must be later either when the values are saved for later reuse or when the URL is built again.
