AD account for "Download Path User" keeps getting locked
On our K1000 the Active Directory account that has read-rights to the software-share on replication sites keeps getting locked. The user how tries to download a piece of software from the lib get the following error message in then local log:
[Thu Jun 05 12:08:47 2014] Error (win) copying files from 'smb://<domain>;<AD-account>:xxxxxxxx@<hostname Repl site>/KACE_DIST/repl2/software/33347/<softwarename>.zip.ed1ca39d8f6fb61e398489b5f3c9dc1a' to 'C:\ProgramData\Dell\KACE\downloads\33347\<softwarename>.zip' : (1909) The referenced account is currently locked out and may not be logged on to
When I check AD the account is locked. When I unlock it the user can download and install the software ok, but after only a short while the account is locked again.
We have 63 replication shares across different servers located at different sites. The account is the same for all sites.
Any clues on what can be causing this and how I can correct it?
