Adjust the word space in the itemize environment

Question

As you can see, there is a too-wide space caused by the long word "AuthenticateWith". Is there any idea to introduce the hyphenation under the {itemize} and somehow adjust the item. I tried \justifying and {ragged2e} but neither of them works fine. Please see the code:

\begin{itemize}

\item The predicate \textbf{\emph{authenticateWith}} is defined to associate \textbf{Federation} and \textbf{Centre} individuals, e.g. \emph{authenticateWith}(\emph{Birmingham03}, \emph{INPDR}) refers to the fact that identity certificates issued from the centre \emph{Birmingham03} can be automatically verified by \emph{INPDR}.

\end{itemize}

I tried to reproduce your problem with this code and it didn't appear so I suggest you to test it with your LaTeX distribution. If the same problem is come back, it's probably your LaTeX version or your version of babel package.

\documentclass[a4paper,12pt]{article}
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}
\usepackage[main=english,frenchb]{babel}
\begin{document}
\begin{minipage}{10cm}

\begin{itemize}
\item The predicate \textbf{authenticateWidth} is defined to associate   \textbf{Federation and Centre individuals}, e.g. \textit{AuthenticateWidth(Birminghamoz, INPDR)} refers to the fact that identity certificates issued from the centre \textit{Birminghamoz} can be automatically verified by INPDR.
\end{itemize}

 \begin{itemize}
 \item The predicate \textbf{\emph{trust}} is defined to associate    \textbf{Centre} individuals, e.g. \emph{trust}(\emph{Udine02}, \emph{Berlin03}) refers to an organisational trust relation between centres \emph{Udine02} and \emph{Berlin03}.
 \end{itemize} 
 \end{minipage}
 \end{document}

As Ian Thompson wrote, I suggest you to send an example of your code to reproduce the problem. It would be very useful to solve your problem and to help others with the same trouble and that a typical rule adopted by professional software developers.
