#

# This change allows for case insenstive comparisons of principals in the keytab

# file.  This is necessary in order to interoperate with old Windows clients

# that use upper case host name components in service principals.

#

# Original BugID is:

# 15592543 SUNBT6885980 Need case-insensitive keytab lookups for MS interop

#

# Note: In the future, the depedent code (SMB), should construct an acceptor

# name that does not contain the host name component in order perform keytab.

# Refer to the 1.10 feature here:

# 	http://k5wiki.kerberos.org/wiki/Projects/Acceptor_Names

# Patch source: in-house
