It may happen that when we try to mount a CIFS resource as external storage from PAM, the mount operation do not succeed after a longer timer than expected and showing it as 'unmounted' even though no error is shown in the top of the pane.
This occurs when the password used to access the CIFS resource contains one or more punctuation symbols.
Why cannot I map a CIFS resource from PAM, if the password to map it contains punctuation symbols?
Any hardware or virtual appliance running any version of PAM Server.
passwordoption in man mount.cifs explicitely says, that you cannot use comma-contained password in the command line.
