Trying to setup SourceTree with all my remote services and for BitBucket Server, the password is not being saved to Keychain and is being asked for each time I open SourceTree.
After checking Keychain Access, I can see passwords for Gitlab CE and GitHub listed and they work fine in SourceTree.
For BitBucket Server, each time I open SourceTree, I need to go into the SourceTree preferences and re-enter the password after editing the account and then enter it again with the ticket box checked for save to keychain for the remote repos to list.
