The following problem description was identified on the mailing list:
"I'm using uP 2.4.4 with AL. After login of a user, I see always "Guest".
I saw in the IntegratedModes.xsl that this value is assigned on param userName.
In PersonDir.xml I set alias displayName with the right value.
It's strage becouse in up 2.4.3 it works but not in up 2.4.4. "
A change was made to UserInstance.java[1] in the processUserLayoutParameters() method that removed code to set the userName.
+ String userName = person.getFullName();
+ if (userName != null && userName.trim().length() > 0)
+ themePrefs.putParameterValue("userName", userName);
