We experience Bugs with Multiline Passwords in Server 26.6.101:
If you create a new entry and add a multiline password, it can not be edited, no matter if it is uncovered or not, neither can I type in the multiline password field nor can i paste something in it. I can however use the password generator. When the entry is saved and reopened, the multiline password can be edited as usual. This occurs with personal as well with shared entries and with Windows client version 26.6.100 and 26.6.101.
I also had a user who created a new shared entry with a multiline password field and the rights for the field were incorrectly created so he had access to the entry in general but not to the multiline password field any more. This only occurred with a combination of Windows client 26.6.100 and Server 26.6.101.
