Reported by tsala @ MDL-58395:

When reviewing the new language strings introduced in this issue, I noticed that they contain "\n". For future reference, "\n" is not displayed in AMOS and so when the strings are translated, the layout is not kept. Thus, it is recommended to not include "\n" in language strings (MDL-67474).

It seems there are a number of auth_ldap language strings containing "\n". If the layout of the text is important, please feel free to create an issue for removing "\n" from the strings.

So this issue is about to:

1. See why those \n chars in lang strings are there.
2. Remove them ensuring that everything continues working ok.
