New my.typo3.org writes different LDAP attributes for new users
Gerrit at review.typo3.org uses the attribute cn to fetch the full user name:
https://gitlab.typo3.org/services/review.typo3.org/gerrit/-/blob/master/assets/etc/gerrit.config#L24
New users in LDAP are now created by typo3com-admin. They have the following attributes
cn=username
displayName=in contrast to e.g. my account, which was created by typo3org long before the new my.typo3.org infrastructure was set up by TYPO3 GmbH:
cn=Stephan Großberndt
displayName=Stephan Großberndt
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
