Hello,
Is there a solution to hide the contact info tab on my user details tab.

Users cannot change password because we are using and LDAP to active directory and changing the password changes the joomla password not the Active Directory password.

Same for the firstname lastname field, these are retrived from within the AD.

I don't know what you mean sorry?

I think i fixed it. I published the contact info tab only for administrators and put the name field to an other tabl so the username is visible in my profiles list view.
