@rullzer @schiessle ideas?

[whositwhatnow]

Had this same issue, you need to select the Log-in credentials, save in database option in the authentication section in external storage. You can then share on the external share. Thats what worked for me

[r3pek]

@whositwhatnow dude, you just saved the day! :) And thinking about it, it makes perfect sense.

@blizzz maybe a warning or an info of some kind if the credentials aren't stored in the database stating that sharing will be disabled?

PS: I'll keep this bug opened until blizzz replies (or any other dev)

[whositwhatnow]

@r3pek The only thing i am Leary of doing this is that the users password is stored in the local database. So if you are using AD/LDAP auth is stores the password, i haven't looked into it further but i hope its encrypted.

[r3pek]

@whositwhatnow yeah.... it's using LDAP user/password. Can't look at it right now but yeah, I think it's encrypted (just not sure how)

[whositwhatnow]

@r3pek I banged my head with this for almost a week. Have a good one!

[rullzer]

@icewind1991 would it make sense to just disable sharing on mountpoint where we don't have the proper credentials?

[pcreadycl]

i have same problem here, any updates?

Hi @whositwhatnow , I am appreciated that you can help me to give me some idea. my English is poor.
it give me the info "data deficiencies" after I select the Log-in credentials, save in database option in the authentication section in external storage, how should I do?
Thanks a lot
