Hello, update on my question.
CHECKING ANOTHER AD-ATTRIBUTE --------------------------------------------------- I just checked the AD-attribute <jpegPhoto>, which also can be used to store pictures in Active Directory (<ldap_user_attr_picture=jpegPhoto>). Doesn't work either ("Internal Error"). CHECKING THE PICTUREFILES -------------------------------------------------- After that, I checked my picture-files (to make sure, there is nothing wrong with them) and I created two picturefiles "from scratch", meaning, I copied my picture into Windows Paint and saved it as .png and as .jpg and even as .bmp. I imported the jpg using powershell: Import-Module ActiveDirectory $photo = [byte[]](Get-Content C:\Thumbs\myself.jpg -Encoding byte) Set-ADUser Alex -Replace @{jpegPhoto=$photo} Set-ADUser Alex -Replace @{thumbnailPhoto=$photo} Still: "Internal Error" when trying to login. Then I used the png using powershell: Import-Module ActiveDirectory $photo = [byte[]](Get-Content C:\Thumbs\myself.png -Encoding byte) Set-ADUser Alex -Replace @{jpegPhoto=$photo} Set-ADUser Alex -Replace @{thumbnailPhoto=$photo} Still: "Internal Error" when trying to login. Then I used the bmp using powershell: Import-Module ActiveDirectory $photo = [byte[]](Get-Content C:\Thumbs\myself.png -Encoding byte) Set-ADUser Alex -Replace @{jpegPhoto=$photo} Set-ADUser Alex -Replace @{thumbnailPhoto=$photo} Last command led to an error, since <thumbnailPhoto> doens't accept bitmap. Still: "Internal Error" when trying to login. My picturefiles are 200x200 pixel and pretty small (png 64 kb, jpg 13 kb, bmp 118 kb). I could work on the picturefiles, if I knew what to change (like compression or dpi). But without any hints, it's like a needle in a haystack. And I don't know if the files are the problem or the AD-attribute or the way, the pictures are stored in AD. Does anyone have an idea?

LDAP-Configuration (om_ldap.cfg) works fine, except for getting thumbnails/pictures stored in Active Directory. If I uncomment the line <ldap_user_attr_picture=thumbnailPhoto> and save the config-file, I cannot login anymore with my Active-Directory-account - OpenMeetings shows an internal error instead. The only AD-account with a picture stored is my own (so far). The AD-attribute ist thumbnailPhoto, so that is correct. Outlook displays my picture, so that works, too. I wouldn't really need AD-stored photos, but I would like my user-accounts to have pictures, so one doesn't just see a lot of questionmarks-profilepictures, when starting a conference without webcam. If I use the LDAP-connection, I can provide a picture for my account, but this picture is discarded the next time I log in. So the ldap-connection configured doesn't let me change openmeetings-accounts permantenly - which is logical, since they are ldap-accounts. I just need a way to provide accounts with pictures. I wouldn't mind configuring them manually. Does anyone know how to provide user-pictures for ldap-accounts? Have a nice day and an even better week, Alex PS: If this already has been discussed and there is an answer I haven't found by myself, I apologize. In that case, can you just send my the link tot he previous discussion?
