My problem is the following. Teachers/Course creators are able to see 2 links on the left course admin links. "Teachers..." and "Students..." amongst other links like, course, backup, restore etc. I want to hide the links "Teachers..." and "Students..." for everybody except the admin. Since I do not want any teacher or course creator to enroll or unenroll students. I tried to modify the function print_course_admin_links() in moodleroot/course/lib.php but modification of that function does not seem to effect the output at all. Can somebody pinpoint and please let me know, which function in which file do I need to modify in order to accomplish this.

Can you please let me know the path and name of the file in the moodle system. Also the function that displays the "Teachers..." and "Students..." links. The best I could hunt down is given above. Also I have modified the code for 1.1, however I am now using 1.3, almost the same code, but somehow on changing the display function, the output on the webpage does not seem to change.

file to edit... blocks/admin/block_admin.php
see sample: (in this sample only admin see the said link but not teachers...change the condition if you need to... of comment the code that you need to hide from admin)
if (isadmin()) {
$admindata[]="<a href=\"$CFG->wwwroot/backup/backup.php?id=$course->id\">".get_string("backup")."...</a>";
$adminicon[]="<img src=\"$CFG->pixpath/i/backup.gif\" height=16 width=16 alt=\"\">";
$admindata[]="<a href=\"$CFG->wwwroot/files/index.php?id=$course->id&wdir=/backupdata\">".get_string("restore")."...</a>";
$adminicon[]="<img src=\"$CFG->pixpath/i/restore.gif\" height=16 width=16 alt=\"\">";
}
Thank you very much. You have hit the nail. However, the code on my installation looks little different(I am using Moodle 1.3.1). But it worked anyway. I defined a variable in config.php called $CFG->TEACHER and $CFG->STUDENT = 0 or 1 depending on if you want to display "Teachers..." and "Students..." links in the admin menu so the the functionality can be changed on fly. Then I modified the code as shown below. Where START and END block indicate the start of my code and end of my code bock.
NOTE: The code in print_course_admin_links() in course/lib.php is almost identical to this, and I was trying to modify that......which did not work!.
