+Subject: [PATCH] Restore krb5_set_default_tgs_ktypes()
+
+Samba only uses the correct name (krb5_set_default_tgs_enctypes) if it
+cannot find the old one in the library, so removing the name causes a
+linker error for existing builds.
+
+(cherry picked from commit 17ee97788611f8f8f4a6bd69968a9499f4db2215)
+
+ticket: 8985
+version_fixed: 1.19.1

+(cherry picked from commit 3e36b25712d940a8e325abc407143634365b51d0)
