How to Unlock repository when we first create in MDM5.5.41.70

hi All,

we have installed new MDM 5.5.41.70 patch, when we create new repository in the console hierarchy.The reposistory is created and locked by default, when we try to unlock it? In the context menu the unlock reposistory option is in disabled and login option is enabled. when we try to login it is asking for the username and password.

we did't set any username and password for the repository.

can any one help out in this issue.

yours
