As best I can I'm going to explain an oddity that is happening to one of our Sharepoint "Mysite" sites.
I received a request for help that this person was trying to log into her Mysite but it wouldn't accept her credentials. Since I'm the Sharepoint Admin, usually I can log into anyone's site but even I couldn't log in. The initial error I received was "user not found".
I went to Central Admin and did a search and her site WAS found.
I looked at her site using the Sharepoint Manager Utility (good utility BTW) and under "Owner" I saw the error "Attempted to perform and unauthorized operation
". I clicked on the elipse hoping I'd be able to actually enter her name as owner, then I received the attached error.
I went to Central Admin > Site Collections > Change site collection administrators and found that she IS listed as the owner but here's the really strange part -- I placed my name as the "Secondary Site Collection Administrator" then I was able to log into her site (as myself).
I went back to the Sharepoint Manager Utility and looked at her account again and now the above mentioned error was not there - she showed up as owner and I showed up as Secondary Owner.
I don't have her password so I'm unable to log in as her so I don't know if placing my name as secondary administrator enables her to log in.
If she's unable to log in still - does anyone have any ideas how I might correct this strangeness?
Sorry to be so long-winded - brevity doesn't appear to be my strong suit and I always try to give as much detail as I can to aid in troubleshooting
