ORIGINAL POST ON CUPS BUGZILLA (HOWEVER, SEEMS LIKE A SAMBA PROBLEM):

When I try to configure my SAMBA printer in CUPS I specify this address:
smb://pisarenk:z7#TD2qm@print/ituniv4-east

But my password contains "#" character. If I enter it directly, then printing works until first restart. After restart the link in CUPS gets cut to something like smb://pisarenk:z7. If I replace the "#" character with "%23" I cannot use the printer. CUPS says that it cannot connect to CIFS.

Part of log:
E [20/Jan/2007:18:07:51 +0100] [Job 34] Session setup failed: NT_STATUS_LOGON_FAILURE
E [20/Jan/2007:18:07:51 +0100] [Job 34] No ticket cache found for userid=1000

E [20/Jan/2007:18:07:52 +0100] [Job 34] Unable to connect to CIFS host, will retry in 60 seconds...

I suspect that it is partly connected to CUPS but rather to Samba, however, I am not sure what to do to fix this.

CUPS 1.2.6
samba 3.0.22-r3

ANSWER FROM CUPS SUPPORT:

This is not a CUPS problem.

Please report this bug to the Samba folks, who will need to fix their smbspool program so that it supports % encoding in the URI.
