only works for logged in BE admin users. I'm not sure if this is intentional, but it looks like a bug to me. I've been looking into this for hours and there doesn't seem to be a way to identify if a non-admin BE user is logged in.
I can reproduce this on 4.2.12 and 4.4.1.

Can be reproduced on 4.4.2 and 4.2.0 as well.
I'm sure I must be missing something really obvious here. Having a TS conditional for logged in BE users looks absolutely trivial. So I apologize if this should really be a support question.
The backend users are logged in and this behaviour is very easy to reproduce.

This behavior seems to be caused around line 339 of typo3/sysext/cms/tslib/index_ts.php
This looks like a bug to me. Having access right should not affect a variable called beUserLogin.
// Now, if there is a backend user logged in and he has NO access to this page, then re-evaluate the id shown!
if ($TSFE->beUserLogin && (!$BE_USER->extPageReadAccess($TSFE->page) || t3lib_div::_GP('ADMCMD_noBeUser'))) { // t3lib_div:: _GP('ADMCMD_noBeUser') is placed here because workspacePreviewInit() might need to know if a backend user is logged in!// Remove user
unset($BE_USER);
$TSFE->beUserLogin = 0;

This problem also appears to affect 4.3.4 with PHP 5.2.4.

Has the user really (at least) read access to the page opened in FE? (can he see the page in BE?)
To me the if-clause sounds reasonable: If a BE-user has no access rights to a page, he should not be in the same context as BE users, having access to the specific page.

Hi,
as this issue is very old. Does the problem still exists within newer versions of TYPO3 CMS (4.5 or 6.1)?
Or did you find another way to achieve what you need?

I just noticed this case in 4.5.
I tried:
[globalVar = BE_USER|user|uid > 0]
[globalVar = TSFE : beUserLogin > 0]
Both of them don't work.
In my case "giving access to the page for the backend-non-admin" helped, like Steffen mentioned. But there might be other cases where this is not an option.

Bug is still there. Version 4.7 is affected too.
In Addition:
Its no TypoScript problem. The whole $GLOBALS['BE_USER'] object is null if the BE_USER is no admin user.
Hotfix:
if(!is_object($GLOBALS['BE_USER'])) {
$GLOBALS['BE_USER'] = t3lib_div::makeInstance('t3lib_tsfeBeUserAuth');
$GLOBALS['BE_USER']->start();
$GLOBALS['BE_USER']->backendCheckLogin();
}

- TYPO3 Version changed from 4.2 to 6.2
This was originally logged against 4.2. I've just tested this still occurs on 6.2 (so I'm updating this as the issue is still current). Maybe we can get a solution at least for the 6.2-branch?
Workaround is to create a userFunc (which can then be used in TypoScript) with something like:
if (!isset($GLOBALS['BE_USER'])) {
\TYPO3\CMS\Core\Core\Bootstrap::initializeBackendUser();
}
if (is_object($GLOBALS['BE_USER']) && !empty($GLOBALS['BE_USER']->user['uid'])) {
return TRUE;
}
return FALSE;

- TYPO3 Version changed from 6.2 to 4.2
The TYPO3 field holds the value of the TYPO3 version this issue was first found/feature was requested. So back to 4.2

Are there any other options without userFunction to do this?
This might be needed for previewing new settings, or disable Google Analytics for Admins & Editors..
If you just want to preview things "locally", this is a quick method without userFunction

Reproduced that $GLOBALS['BE_USER'] is NOT instantiated in FE, unless the currently logged on Back-End user happens to be an Administrator, contrary to documentation.
Confirmed the hotfix posted in entry number 8 to work-around this bug.

I did a test on both 6.2.15 and 7.6-dev (latest master) with the following code:
[globalVar = BE_USER|user|uid > 0] page.8=TEXT page.8.value=HI I am logged [global] [globalVar = TSFE : beUserLogin > 0] page.9=TEXT page.9.value=Hi I am logged 2 [global]
and I logged with a non-admin user: the result is that both strings are visible.
Could you check again, and confirm? Thank you.

For TYPO3 >= 6.2: as long as the backend user has read access to the current page both TSFE:beUserLogin and BE_USER:user are set correctly.
For pages without read access the workaround that worked for me looks like:
if (!isset($GLOBALS['BE_USER'])) {
$GLOBALS['BE_USER'] = $GLOBALS['TSFE']->initializeBackendUser();
}
Not sure what the side effects are though.
The whole issue might be related to #45625.
