Lost shares when using external storage and LDAP Backend

sistemas_nnttr · March 23, 2017, 12:35pm

Hi all,

this is the second time: when you have users with external storage (CIFS), and these users have shared folders or files, if connecion with LDAP server is lost, all shares are lost!!! LDAP server is used for owncloud user backend and for validating the user configured in the external storage connection to CIFS…

I have lot of shares, so this is a very important problem…

any help would be very appreciated…

Best regards,
JJ.-
