        2.  
          A user is created even if double quotation marks or single quotation marks are specified in a password
      2. CIFS issues
        1.  
          Cannot enable the quota on a file system that is appended or added to the list of homedir
        2.  
          Deleting a CIFS share resets the default owner and group permissions for other CIFS shares on the same file system
        3.  
          Default CIFS share has owner other than root
        4.  
          CIFS mapuser command fails to map all the users from Active Directory (AD) to all the NIS/LDAP users
        5.  
          CIFS share may become unavailable when the CIFS server is in normal mode
        6.  
          CIFS share creation does not authenticate AD users
        7.  
          If you mount or access a CIFS share using the local user without netbios or cluster name, the operation fails
        8.  
          During upgrade, the CVM and CFS agents are not stopped
      3. FTP issues
        1.  
          If a file system is used as homedir or anonymous_login_dir for FTP, this file system cannot be destroyed
        2.  
          The FTP> server start command reports the FTP server to be online even when it is not online
        3.  
          The FTP> session showdetails user=<AD username> command does not work
        4.  
          If the security in CIFS is not set to Active Directory (AD), you cannot log on to FTP through the AD user
        5.  
          If security is set to local, FTP does not work in case of a fresh operating system and Veritas Access installation
        6.  
          If the LDAP and local FTP user have the same user name, then the LDAP user cannot perform PUT operations when the security is changed from local to nis-ldap
        7.  
          FTP with LDAP as security is not accessible to a client who connects from the console node using virtual IPs
        8.  
          The FTP server starts even if the home directory is offline and if the security is changed to local, the FTP client writes on the root file system

The operating system names of fencing disks are not consistent across the Veritas Access cluster that may lead to issues

The disks that are used for fencing across the cluster may not have the same operating system names. For example, a disk that is called sda on one node may be called sdf on another node. This means that the sda disk on both the nodes are not the same. This can lead to writes on unintended disks when setting up disk-based SCSI3 fencing.

(IA-11893)

Workaround:

Ensure that the same operating system disk names are used for all the disks that are used for fencing across the cluster.
