but i didnt find out what exactly is missing for a XenApp user. the interesting thing about this problem is: if a user logs on to a machine once with RDP or a full desktop, it works afterwards with published apps too. in non-persistent environments (PVS, MCS), this only works until the XenApp server is rebooted.<\/p>\n<p>Citrix contacted Microsoft about this issue and after some weeks they came back to me with this findings:<\/p>\n<p><i>&#8220;RemoteApp and XenApp are sort of special case of logon as they don&#8217;t run thru a full desktop logon experience. The problem is, for XenApp the record for the user account is NOT created in the User table in the state repository machine database (%ProgramData%\\Microsoft\\Windows\\AppRepository\\StateRepository-Machine.srd).<br \/>\nWhen there is no user record available in the User table, looking up what associated apps are avail for the user in response of clicking a URL fails, which leads to the issue.&#8221;<\/i><\/p>\n<p>they dont provide a fix for this problem yet and they told me that its going to take some time to develop one. so i thought &#8211; lets have a look at this file and its contents &#8211; maybe i can somehow fix it manually, until Citrix comes up with a solution.<\/p>\n<p>using a hex editor, i found out that this file is an sqlite database:<\/p>\n<p><a href=\"http:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/hex_editor.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-228 size-large\" src=\"http:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/hex_editor-1024x505.png\" alt=\"\" width=\"1024\" height=\"505\" srcset=\"https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/hex_editor-1024x505.png 1024w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/hex_editor-300x148.png 300w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/hex_editor-768x379.png 768w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/hex_editor-1170x577.png 1170w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/hex_editor.png 1432w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a>now, that is interesting (because we can edit it and i didnt expect Microsoft using SQLite, because they have their own databases). i had a deeper a look at it with <a href=\"http:\/\/sqlitebrowser.org\/\">SQLite Browser<\/a>. to open the database, i had to use psexec -e -i -s (because only SYSTEM has read\/write on this database).<\/p>\n<p><a href=\"http:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/sqlite_browser.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-235 size-large\" src=\"http:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/sqlite_browser-1024x574.png\" alt=\"\" width=\"1024\" height=\"574\" srcset=\"https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/sqlite_browser-1024x574.png 1024w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/sqlite_browser-300x168.png 300w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/sqlite_browser-768x430.png 768w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/sqlite_browser-1170x655.png 1170w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/sqlite_browser.png 1578w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a>and there we have indeed a User table (like Microsoft stated in their findings) and this table does not contain a lot of data (which is good for us).<\/p>\n<p><a href=\"http:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/user_table.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-238 size-large\" src=\"http:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/user_table-1024x349.png\" alt=\"\" width=\"1024\" height=\"349\" srcset=\"https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/user_table-1024x349.png 1024w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/user_table-300x102.png 300w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/user_table-768x261.png 768w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/user_table-1170x398.png 1170w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a>there is just an entry for each user, where _Revision is set to 1 and the BLOB containing the SID in binary format. this is identical to the objectSid attribute, that we can find in ADUC attribute editor.<\/p>\n<p><a href=\"http:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/objectsid.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-240 size-full\" src=\"http:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/objectsid.png\" alt=\"\" width=\"814\" height=\"562\" srcset=\"https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/objectsid.png 814w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/objectsid-300x207.png 300w, https:\/\/kolbi.cz\/blog\/wp-content\/uploads\/2017\/09\/objectsid-768x530.png 768w\" sizes=\"auto, (max-width: 814px) 100vw, 814px\" \/><br \/>\n<\/a>for a PoC i just added a user manually to this database using SQLite Browser and the SID from ADUC &#8211;
