Customer has an issue when he modified credential (internal error in communication channel).
I thougth that this issue deal with bugid CSCtd07131 but we still have the issue even if we had installed the fix given by the tac.
For example, if we change the display name on identity properties we have an error message : internal error in communication channel.
After installing the fix, we have cleaned ie cache from the browser.
Do you think I need to reopen a case to the tac or may be I need to make an other action ?
Many thanks, Elisabeth
