CIFS filesystem mount problem

When we are trying to mount the following windows share, using CIFS the bellow problem is arise

mount -vvv -t cifs //192.168.22.231/aaf_docs/SEFPLLIVE_20032013/InterfaceOutput/Payables/OraclePayables -o username=admin,password=Passw0rd /mnt
mount.cifs kernel mount options: unc=//192.168.22.231\aaf_docs,ip=192.168.22.231,ver=1,rw,username=admin,prefixpath=SEFPLLIVE_20032013/InterfaceOutput/Payables/OraclePayables,pass=********
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)

But if we rename the windows share named "OraclePayables" to "OraPayables" then it is mounted successfully.
This is a windows production server share and we don't change the share folder name. Our Linux version is Red Hat Enterprise Linux 5.
